Experimental investigation on thermo hydraulic performance of ferronanofluid flow in a dimpled tube under magnetic field effect

ABSTRACT Active and passive techniques have been utilized together to enhance heat transfer in this study. The ferronanofluid, magnetic field, and dimpled tube have not been utilized together in the literature so far. Regarding this issue, this investigation is the first experimental study to specify the effect of use of these three effects simultaneously. The concept of this study is to determine the thermo-hydraulic performance of Fe3O4/H2O flow inside a dimpled tube under magnetic field effect. Constant and uniform heat flux of 4500 W/m2 has been applied on the surface of the tube. The work aims to gain data in the range of laminar flow (1131≤ Re≤2102) in the dimpled tube. Dimple geometry with pitch ratio of P/d = 3.75, magnetic field (B = 0.03 ≤ T ≤ 0.16), and nanoparticle volume fraction of 1.0% are the base variables. The results showed that Nusselt number increases with increasing Reynolds number and magnetic field intensity. The highest increase in Nusselt number is obtained as 115.31% compared with the distilled water flow in the smooth tube for the case of magnetic field intensity of 0.3 T. The highest Performance Evaluation Criteria value is also determined as 1.44 for the case of ferronanofluid flow in dimpled tube at Re = 1131 in absence of magnetic field.

Plasmonic excitation for a tunable transmitter without magnetic field immune to backscattering

We predict a plasmonic excitation that exhibits chiral properties in the absence of external magnetic field. This excitation, that we call an interedge chiral Berry plasmon (IE CBP), is bound to an interface between two two-dimensional electron systems with different anomalous Hall conductivities. Crucially, the IE CBP is a unidirectional mode whose propagation direction and frequency are susceptible to external control, in sharp contrast to state-of-the-art magnetic field-free devices. We believe that the IE CBP represents a unique platform for tunable backscattering-immune signal transmission in the absence of magnetic field.

Impacts of using an elastic fin on the phase change process under magnetic field during hybrid nanoliquid convection through a PCM-packed bed system

In this work, combined utilization of an elastic fin and magnetic field on the phase change process dynamics is numerically assessed during nanoliquid convection in a phase change material (PCM)-packed bed embedded cylindrical reactor. Impacts of Reynolds number (Re between 100 and 700), elastic modulus of fin (between 104 and 109), strength of the magnetic field (Ha between 0 and 100), length (between 0.2L and 0.6L) and vertical location (between 0.1H2 and 0.6H2) of the elastic fin on the phase change dynamics are numerically explored. Acceleration of the phase change process is observed by using an elastic fin as compared to a rigid one. The reduction of the phase completion time (t-pc) becomes 22.8% when cases at the highest and lowest Re are compared with flexible fin at the lowest elastic modulus. The magnetic field is effective when it is used with flexible fin of different size and for various vertical locations from the PCM zone. The reduction of the t-pc is obtained as 53% when cases with the lowest and highest vertical locations are compared in the absence of magnetic field while it is only 8.5% with magnetic field at the highest strength. Elastic fin with radially acting magnetic field provides an excellent contribution for controlling the phase change dynamics in a PCM-installed cylindrical reactor.

Combined Effects of Sequential Velocity and Variable Magnetic Field on the Phase Change Process in a 3D Cylinder Having a Conic-Shaped PCM-Packed Bed System

Effects of sequential velocity and variable magnetic field on the phase change during hybrid nanofluid convection through a 3D cylinder containing a phase-change material packed bed (PCM-PB) system is analyzed with the finite element method. As the heat transfer fluid, 40% ethylene glycol with hybrid TiO2-Al2O3 nanoparticles is considered. Impacts of the sequential velocity parameter (K, between 0.5 and 1.5), geometric factor of the conic-shaped PCM-PB (M, between 0.2 and 0.9), magnetic field strength (Ha number between 0 and 50) and solid volume fraction of hybrid nanoparticles (vol.% between 0.02% and 0.1%) on the phase change dynamics are explored. Effects of both constant and varying magnetic fields on the phase change process were considered. Due to the increased fluid velocity at the walls, the phase change becomes higher with higher values of the sequential velocity parameter (K). There is a 21.6% reduction in phase transition time (tF) between the smallest and highest values of K both in the absence and presence of a constant magnetic field. The value of tF is reduced with higher magnetic field strength and the amount of reduction depends upon the sequential velocity parameter. At K = 1.5, the reduction amount with the highest Ha number is 14.7%, while it is 26% at K = 0.5. When nanoparticle is loaded in the base fluid, the value of tF is further reduced. In the absence of a magnetic field, the amount of phase-transition time reduction is 6.9%, while at Ha = 50, it is 11.7%. The phase change process can be controlled with varying magnetic field parameters as well. As the wave number and amplitude of the varying magnetic field are considered, significant changes in the tF are observed.

Heat transfer enhancement in stagnation point flow of ferro-copper oxide/water hybrid nanofluid: A special case study

This present work is to investigate the behavior of Fe3O4−CuO/H2O hybrid-type nanofluid flow toward a magnetic field for enhancing the thermal transfer by horizontal stretchable surface. In the base fluid different tiny-sized nanoparticles collides and enhanced the heat transformation in the absence of magnetic field. Here the combinations of Fe3O4−CuO/H2O as hybrid nanofluids and CuO/H2O as nanofluid are implemented. The Ferro and Copper oxide are dispersed in water base fluid. Such Ferro nanomaterials are more fruitful in production technology, protein absorption, catalysis, medical technology and environment. The implementation of Fe3O4 NPs in medical science mainly involves targeted drug/gene delivery, biosensor, magnetic resonance imaging (MRI), contrast improvement and hyperthermia, biophotonics, detection of cancer cells, diagnosis and magnetic field-assisted radiotherapy and tissue engineering. Copper oxide used as a catalyst for increasing the rate of combustion in rocket propellant. It may significantly increase the homogenous propellant burning rate, lower the pressure index, and boost the effectiveness of the AP composite propellant as a catalyst. In additional, the governing coupled dimensional equations are reduced into the ordinary once with associated the suitable similarities. The resultant dimension-less expressions are programmed in the computational MATLAB software via bvp4c solver with shooting scheme. The important outcomes of this investigation are the behavior of numerous good parameters including stretching ratio parameterA∗, magnetic parameterβ, volumetric frictions for nanoparticlesφ, suction/injection parameterfw and thermal radiation parameterRd. The physical behavior of above discussed sundry parameters is described through figures. The dispersion of Fe3O4 and CuO in water-based fluid significantly improved the phenomenon of heat transfer. Results found that the velocity field is escalates when the stretching ratio parameter is enhanced. Furthermore, larger values of the suction/injection parameter causes a reduction in velocity profile for A<1 and A>1. The induced magnetic field is improved with larger estimations of the nanoparticle fraction. Thermal field is escalates by growing thermal radiation parameter and Eckert number. It is further observed that temperature profile is reduces by increasing stretching ratio parameter. From the analysis we noted that skin friction is raises via larger estimations of magnetic parameter.

Interplay between singlet and triplet pairings in multiband two-dimensional oxide superconductors

We theoretically study the superconducting properties of multi-band two-dimensional transition metal oxide superconductors by analyzing not only the role played by conventional singlet pairings, but also by the triplet order parameters, favored by the spin-orbit couplings present in these ma- terials. In particular, we focus on the two-dimensional electron gas at the (001) interface between LaAlO3 and SrTiO3 band insulators where the low electron densities and the sizeable spin-orbit couplings affect the superconducting features. Our theoretical study is based on an extended su- perconducting mean-field analysis of the typical multi-band tight-binding Hamiltonian, as well as on a parallel analysis of the effective electronic bands in the low-momentum limit, including static on-site and inter-site intra-band attractive potentials under applied magnetic fields. The presence of triplet pairings is able to strongly reduce the singlet order parameters which, as a result, are no longer a monotonic function of the charge density. The interplay between the singlet and the triplet pairings affects the dispersion of quasi-particle excitations in the Brillouin zone and also induces anisotropy in the superconducting behavior under the action of an in-plane and of an out- of-plane magnetic fields. Finally, non-trivial topological superconducting states become stable as a function of the charge density, as well as of the magnitude and of the orientation of the magnetic field. In addition to the chiral, time-reversal breaking, topological superconducting phase, favored by the linear Rashba couplings and by the on-site attractive potentials in the presence of an out- of-plane magnetic field, we find that a time-reversal invariant topological helical superconducting phase is promoted by not-linear spin-orbit couplings and by the inter-site attractive interactions in the absence of magnetic field.

Effect of magnetic fields on the efficiency of the photocatalytic degradation of methylene blue in a dynamic fluid system

Methylene blue dye can induce negative effects to aquatic life and the environmental system. So, it is important to remove it from water. Although, the photocatalytic degradation of dye solution during magnetic treatment (or static water process) can increase the dye degradation, but it cannot apply for a large wastewater. Therefore, the dynamic fluid system is required. This paper investigated the effect of magnetic fields (MFs) through dynamic fluid magnetization system on the degradation of dye solution. Ultraviolet (UV) irradiation experiments were carried out in the presence of zinc oxide (ZnO) catalyst. The experiment was divided into two parts. First, the dye solution was exposed to MFs multiple times. In the second part, the dye solution was exposed to MFs continuously using a dynamic fluid system. The results indicated that the dye solution degraded faster when the exposure time to MFs under dynamic fluid system was long. At least 60% of the dye solution degraded within 3 min when the MF of strength 600 mT was applied. On the other hand, the dye solution degraded by only 24% in the absence of MFs. The degradation mechanism was observed to fit the pseudo-first-order kinetic reaction. The rate constant of the reaction was higher in the presence of MFs than that in the absence of MFs. This resulted in better degradation performance. Therefore, it can be concluded that the photocatalytic degradation of the dye solution was enhanced when external MFs were applied to magnetize dye solution using dynamic fluid system.

Kubo estimation of the electrical conductivity for a hot relativistic fluid in the presence of a magnetic field

We have explored the multi-component structure of electrical conductivity of relativistic Fermionic and Bosonic fluid in presence of magnetic field by using Kubo approach. This is done by explicitly evaluating the thermo-magnetic vector current spectral functions using the real time formalism of finite temperature field theory and the Schwinger proper time formalism. In absence of magnetic field, the one-loop diagramatic representation of Kubo expression of any transport coefficients is exactly same with relaxation time approximation (RTA) based expression, but this equality does not hold for finite magnetic field picture due to lacking of proper implementation of quantum effect in latter approach. We have shown this discrepancy for particular transport coefficient - electrical conductivity, whose starting point in Kubo approach will be electromagnetic current-current correlator and its one-loop skeleton diagram carrying two scalar/Dirac propagators for scalar/Dirac fluid. Through a numerical comparison between RTA and Kubo expressions of conductivity components (parallel and perpendicular), we have attempted to interpret detail quantum field theoretical effect, contained by Kubo expression but not by RTA expression. In classical RTA expression we get magnetic field independent parallel conductivity due to zero Lorentz force but in field theoretical Kubo expression, it decreases and increases with the magnetic field for scalar and Dirac medium respectively due to Landau quantization effect. This parallel component of conductivity can be interpreted as zero momentum limit of quantum fluctuation with same Landau level internal lines. While for perpendicular component of conductivity, fluctuation with Landau level differences $\pm 1$ are noticed, which might be a new realization of transportation in field theoretical sector.

Chiral splitting of Kondo peak in triangular triple quantum dot

New characteristics of the Kondo effect, arising from spin chirality induced by the Berry phase in the equilibrium state, are investigated. The analysis is based on the hierarchical equations of motion (HEOM) approach in a triangular triple quantum-dot (TTQD) structure. In the absence of magnetic field, TTQD has four-fold degenerate chiral ground states with degenerate spin chirality. When a perpendicular magnetic field is applied, the chiral interaction is induced by the magnetic flux threading through TTQD and the four-fold degenerate states split into two chiral state pairs. The chiral excited states manifest as chiral splitting of the Kondo peak in the spectral function. The theoretical analysis is confirmed by the numerical computations. Furthermore, under a Zeeman magnetic field B, the chiral Kondo peak splits into four peaks, owing to the splitting of spin freedom. The influence of spin chirality on the Kondo effect signifies an important role of the phase factor. This work provides insight into the quantum transport of strongly correlated electronic systems.

Evaporation and drying characteristics of the sessile ferrofluid droplet under a horizontal magnetic field

In this study, the evaporation characteristics and drying patterns of various sessile ferrofluid droplets on certain substrate under horizontal magnetic fields of controlled intensities are reported. The effects of droplet concentration and magnetic field intensity on the duration of each evaporation stage and drying patterns of droplets have been systematically investigated. It turned out that a plateau appears at the initial stage of evaporation in the absence of magnetic field and it was found that the plateau value is positively correlated with the concentration of ferrofluid droplets. Under the external magnetic field, the evaporation time of droplets decreases, the stage of contact line retreat extends, the stage of late pinning mode shortens, and the deposition area of ferrofluid droplet decreases compared to that of without magnetics field. The deposition area increases gradually and becomes more uniform with the increase of magnetic field. The decrease of friction force which is due to the decrease of the number of nanoparticles at the contact line under external magnetic field is the main reason for the observed phenomena. We found that the coffee ring and the uniform deposition inside the droplet will be destroyed when the magnetic field intensity is higher than a critical value. Our work has a significant reference value for the evaporation of sessile magnetic fluid droplets under the applied magnetic field, especially when the drying pattern needs to be precisely controlled, such as in spray or biomedicine.

Engineering plasmon modes and their loss in armchair graphene nanoribbons by selected edge-extended defects

The effect of edge modification of armchair graphene nanoribbons (AGNRs) on the collective excitations are theoretically investigated. The tight-binding method is employed in conjunction with the dielectric function. Unconventional plasmon modes and their association with the flat bands of the specially designed AGNRs are thoroughly studied. We demonstrate the robust relationship between the novel collective excitations and both the type and period of the edge modification. Additionally, we reveal that the main features displayed in the (momentum, frequency)-phase diagrams for both single-particle and collective excitations of AGNRs can be efficiently tuned by edge-extended defects. Our obtained plasmon modes are found to be analogous to magnetoplasmons associated with collective excitations of Landau-quantized electrons. This work provides a unique way to engineer discrete magnetoplasmon-like modes of AGNRs in the absence of magnetic field.

Wheatstone bridge based offset cancelling method utilizing a JFET as a voltage-controlled resistor

We designed and investigated an offset cancelling circuit based on a Wheatstone bridge at the output of a Hall-effect sensor. This circuit not only cancelled the offset voltage caused by unintentional Hall probe misalignment but also provided a voltage gain. The Wheatstone bridge circuit consisted of a JFET, two fixed resistors and a variable resistor. In the absence of magnetic field, the JFET was used as a voltage-controlled resistor and its channel resistance was determined by the Hall offset voltage. To compensate the node voltage induced in the JFET channel with the non-zero Hall offset voltage, the variable resistor in the bridge circuit was adjusted to produce the cancelled output voltage between the two bridge nodes. The difference output of the bridge nodes acted as the offset cancelled Hall voltage. When the magnetic field was applied, the branch with the JFET acted as a common source amplifier with the input from the measured Hall voltage. Therefore, the difference output represented the amplified offset cancelled Hall voltage with the magnetic field. The operating point of the amplifier was chosen for linearity and its gain was measured to be 26.4.

Surface theory of a second-order topological insulator beyond the Dirac approximation

We study the surface states and chiral hinge states of a 3D second-order topological insulator in the presence of an external magnetic gauge field. Surfaces pierced by flux host Landau levels, while surfaces parallel to the applied field are not significantly affected. The chiral hinge modes mediate spectral flow between neighbouring surfaces. As the magnetic field strength is increased, the surface Landau quantization deviates from that of a massive Dirac cone. Quantitatively, the $n = 0$ Landau level falls inside the surface Dirac gap, and not at the gap edge. The $n \ne 0$ levels exhibit a further, qualitative discrepancy: while the massive Dirac cone is expected to produce pairs of levels ($\pm n$) which are symmetric around zero energy, the $n$ and $-n$ levels become asymmetric in our lattice model -- one of the pair may even be absent from the spectrum, or hybridized with the continuum. In order to resolve the issue, we extend the standard 2D massive Dirac surface theory, by including additional Hamiltonian terms at $\mathcal{O} (k^2)$. While these terms do not break particle-hole symmetry in the absence of magnetic field, they lead to the aforementioned Landau level asymmetry once the magnetic field is applied. We argue that similar $\mathcal{O}(k^2)$ correction terms are generically expected in lattice models containing gapped Dirac fermions, using the BHZ model of a 2D topological insulator as an example.

Magnetic diffusion and interaction effects on ultrahigh energy cosmic rays: Protons and nuclei

The flux of ultrahigh energy cosmic rays reaching the Earth is affected by the interactions with the cosmic radiation backgrounds as well as with the magnetic fields that are present along their trajectories. We combine the SimProp cosmic ray propagation code with a routine that allows to account for the average effects of a turbulent magnetic field on the direction of propagation of the particles. We compute in this way the modification of the spectrum which is due to the magnetic horizon effect, both for primary nuclei as well as for the secondary nuclei resulting from the photo-disintegration of the primary ones. We also provide analytic parameterizations of the attenuation effects, as a function of the magnetic field parameters and of the density of cosmic ray sources, which make it possible to obtain the expected spectra in the presence of the magnetic fields from the spectra that would be obtained in the absence of magnetic fields. The discrete nature of the distribution of sources with finite density also affects the spectrum of cosmic rays at the highest energies where the flux is suppressed due to the interactions with the radiation backgrounds, and parameterizations of these effects are obtained.

Co0.5Mn0.5Fe2O4@PMMA Nanoparticles Promotes Preosteoblast Differentiation through Activation of OPN-BGLAP2-DMP1 Axis and Modulates Osteoclastogenesis under Magnetic Field Conditions.

The prevalence of osteoporosis in recent years is rapidly increasing. For this reason, there is an urgent need to develop bone substitutes and composites able to enhance the regeneration of damaged tissues which meet the patients’ needs. In the case of osteoporosis, personalized, tailored materials should enhance the impaired healing process and restore the balance between osteoblast and osteoclast activity. In this study, we fabricated a novel hybrid material (Co0.5Mn0.5Fe2O4@PMMA) and investigated its properties and potential utility in the treatment of osteoporosis. The material structure was investigated with X-ray diffraction, Fourier-transform infrared spectroscopy with attenuated total reflectance, FTIR-ATR, transmission electron microscopy (TEM), scanning electron microscopy (SEM) and selected area (electron) diffraction (SAED). Then, the biological properties of the material were investigated with pre-osteoblast (MC3T3-E1) and pre-osteoclasts (4B12) and in the presence or absence of magnetic field, using RT-qPCR and RT-PCR. During the studies, we established that the impact of the new hybrids on the pre-osteoblasts and pre-osteoclasts could be modified by the presence of the magnetic field, which could influence on the PMMA covered by magnetic nanoparticles impact on the expression of genes related to the apoptosis, cells differentiation, adhesion, microRNAs or regulating the inflammatory processes in both murine cell lines. In summary, the Co0.5Mn0.5Fe2O4@PMMA hybrid may represent a novel approach for material optimization and may be a way forward in the fabrication of scaffolds with enhanced bioactivity that benefits osteoporotic patients.

Topological spin textures in a two-dimensional MnBi2(Se, Te)4 Janus material

Realizing and controlling topological spin textures are widely attractive for their promising applications in information and communication technology. Here, using first-principles calculations and micromagnetic simulations, a stable magnetic Janus material MnBi2(Se, Te)4 with an inherent Dzyaloshinskii–Moriya interaction is proposed to stabilize a variety of topological magnetic structures under temperature and magnetic fields. Furthermore, a sub-10 nm skyrmion can spontaneously form in the absence of magnetic fields in MnBi2(Se, Te)4 by using van der Waals heterostructure engineering. These results provide a promising route for the generation and modulation of topological spin textures in two-dimensional spintronic devices.

The effect of repetitive magnetic and cyclic loading on the fatigue life prediction of a magnetorheological elastomer

Prediction of fatigue life is particularly crucial in magnetorheological elastomer (MRE) based rubber components, especially when are exposed to repetitive magnetic and cyclic loading. MREs are smart composites that contain soft elastomer matrix and carbonyl iron particles (CIPs). In this research, silicon rubber was mixed with 20% of CIPs in the absence of an external magnetic field to produce MREs. Firstly, for the determination of material constants (including hyper elastic, magnetic, and viscoelastic), two types of tests such as uniaxial compression and relaxation, were performed on the samples. Then, fatigue tests were performed by a servo-hydraulic fatigue testing machine with cyclic loading in a repetitive magnetic field. Fatigue equations were obtained based on the number of fatigue life and maximum stress. The results confirmed that maximum stress could be used as a trustworthy fatigue life predictor for MREs when they are subjected to a combination of repetitive magnetic and cyclic loading. Scanning electron microscopy images from fatigue crack showed that the internal structure of MREs became stronger in the direction of the magnetic field. The maximum stress of the MRE was smaller in the absence of a magnetic field and decreased as the number of fatigue cycles increased with and without the magnetic field.

Shear viscosity and electrical conductivity of the relativistic fluid in the presence of a magnetic field: A massless case

We have explored the shear viscosity and electrical conductivity calculations for bosonic and fermionic media, without and with presence of an external magnetic field. For numerical visualisation, we have dealt with their simplified massless expressions. In the presence of a magnetic field, five independent velocity gradient tensors can be designed, and so their corresponding proportional coefficients, connected with the viscous stress tensor, provide us five components of the shear viscosity coefficient. In the existing literature, two sets of viscous stress tensors are available. Starting from them, the present work has obtained expressions for two sets of five shear viscosity coefficients, which can be ultimately classified into three basic components – parallel, perpendicular and Hall components as one get similar expression for the electrical conductivity at the finite magnetic field. Our calculations are based on the kinetic theory approach in relaxation time approximation. Repeating the same mathematical steps under finite magnetic field, which is traditionally practiced in the absence of magnetic field, we have obtained two sets of five shear viscosity components, whose final expressions are in good agreements with earlier references, although a difference in methodology or steps can be noticed. In this context, the present work, for the first time, addresses a detailed calculation of relaxation time approximation (RTA)-based kinetic theory calculations of the second set of five shear viscosity components, which was previously done by Denicol et al (Phys. Rev. D 98, 076009 (2018)) in moment method technique. Realising the massless results of viscosity and conductivity for Maxwell–Boltzmann, Fermi–Dirac and Bose–Einstein distribution functions, we have applied them for massless quark gluon plasma and hadronic matter phases, which can provide us a rough order of strength, within which actual results will vary during quark–hadron phase transition. The present work also indicates that the magnetic field might have some role in building perfect fluid nature in RHIC or LHC matter. The lower bound expectation of shear viscosity to entropy density ratio is also discussed. Here, for the first time, we are addressing an analytic expression of temperature- and magnetic field-dependent relaxation time of the massless fluid, for which perpendicular component of shear viscosity to entropy density ratio can reach its lower bound.

Control of Néel-type Magnetic Kinks Confined in a Square Nanostructure by Spin-Polarized Currents

Magnetic skyrmion in chiral magnet exhibits a variety of unique topological properties associated with its innate topological structure. This inspires a number of ongoing searching for new topological magnetic textures. In this work, we used micromagnetic simulations and Monte Carlo simulations to investigate an exotic Néel-type magnetic kinks in square-shaped nanostructures of chiral magnets, which performs rather stably in the absence of magnetic field. The individual magnetic kink can reside in one of the four possible corners, and carry possibly upward or downward core polarity, constituting eight degenerate states. In addition, these kinks also exhibit unique behaviors of generation, stability and dynamics, as revealed by micromagnetic simulations. It was found that such kinks can be created, annihilated, displaced, and polarity-reversed on demand by applying a spin-polarized current pulse, and are easily switchable among the eight degenerate states. In particularly, the kinks can be switched toward the ferromagnetic-like states and backward reversibly by applying two successive current pulses, indicating the capability of writing and deleting the kink structures. These findings predict the existence of Néel-type magnetic kinks in the square-shaped nanostructures, as well as provide us a promising approach to tailor the kinks by utilizing the corners of the nanostructures, and control these states by spin-polarized currents. The present work also suggests a theoretical guide to explore other chiral magnetic textures in nanostructures of polygon geometries.

Nanoscale energy transport of inclined magnetized 3D hybrid nanofluid with Lobatto IIIA scheme

AbstractKey developments in the field of nanotechnology have drawn the attention of many scholars toward the interaction of nanoparticles due to their capturing applications in solar energy systems and thermal engineering. Larger consumption of energy posed a challenge for thermal science, so thermal engineering is trying to solve this issue by increasing the thermal conductivity of the fluid. The thermal conductivity of conventional fluid is increased by incorporating the nanoparticles in the base fluid. Keeping this in mind, the present research project addresses the utilization of nanoparticles in a steady three‐dimensional rotating flow of magnetohydrodynamic water‐based hybrid fluid over an extending sheet. Nanoparticles of aluminum oxide (Al2O3) and silver (Ag) are being used with water (H2O) as base fluid. The velocity of nanoparticles is being captured under the influence of an inclined magnetic field and the transport of heat is scrutinized through thermal radiation. The physical model generates partial differential equations and then transported into an equivalent set of a nonlinear ordinary differential equations. The purpose of numerical computation is made by the Lobatto IIIA method, which is a type of Matlab scheme bvp4c and based on the finite difference method. Geometry of velocity profile is explained with different parameters in presence and absence of magnetic field and energy of hybrid nanofluid is explained under the influence of the inclined and perpendicular magnetic field. Gradual increment inϑbothfandgprofiles because strengthen the magnetic field results lower velocity. An increment in nanoparticle concentration of Al2O3andAggives a larger magnitude of velocity. The rotation parameter shows the rotation of nanoparticles; due to these rotations both linear and angular components of velocity increase in the presence and absence of a magnetic effect.
