Magneto-Hydrodynamic effects on Diesel/CNG bubbly flow enhanced by Fe3O4 Nanoparticles: Experimental and mathematical assessments

In the present study, the magneto hydrodynamic (MHD) was applied to the motion analysis of compressed natural gas (CNG) bubbles in laminar diesel flow after enhancing the liquid fuel with iron oxide nanoparticles (Fe3O4) in a horizontal pipe using experimental and mathematical approaches. Two distinct techniques were adopted for the experimental measurements: High speed video camera system (HSVC) and particle image velocimetry (PIV). The result of the PIV investigation indicates that increasing the intensity of the magnetic field changed the axial velocity profile of the diesel/nanoparticle mixture from the parabolic to a relatively flat shape. Whilst to illustrate the effect of magnetic field on bubble velocity, the axial and vertical components of the bubble velocity were computed by keeping track of the geometric center of the bubble from frame to frame recorded by HSVC. Moreover, the fundamental equation of motion of a single CNG bubble based upon Newton’s law under a forced magnetic field were derived and presented. The origination processes of the velocity dispersion of the liquid and gas stages of the bubbly flow were equally discussed. The governing partial-differential equations were numerically determined by means of a 4th order Runge-Kutta method. The outcomes from the model solution indicate that at magnetic field intensity (B = 0), the comparison between mathematical and experimental results in literature for the average axial and perpendicular components of bubble velocity resulted in mean percentage differences of 10.4 % and 15.6 % respectively.

Principles of Magnetohydrodynamical Control of Internal and External Supersonic Flows

This paper demonstrates the possibility of active magnetohydrodynamic (MHD) control of supersonic flows containing shock waves. The shock wave configurations that occur at the inlet to a supersonic diffuser and in front of a streamlined semicylindrical model are used for the purpose of investigation. The impact is carried out by organizing local gas discharge regions when applying a magnetic field transverse to gas discharge currents. It has been shown that by changing the local region of application, the intensity and the direction of the gas discharge currents, it is possible to change the intensity and direction of the ponderomotive force acting on the gas flow during MHD interaction. The ponderomotive force control allows for acting locally on the shape and position of shock waves, the speed and direction of the flow, and the increase or reduction of pressure near the surface of the streamlined body. The experiments were carried out on a gas dynamic setup based on a shock tube in a gas dynamic path, capable of creating supersonic flows in a wide range of Mach numbers at M = 4–7. There was a possibility of organizing the electric and pulsed magnetic fields with an intensity of up to 1.5 T. The given experimental Schlieren flow patterns and the analysis of the obtained data demonstrate the MHD effect on: the change in the angle of inclination of the attached shocks, both into increase and decrease; the bow shock wave approaching the body or the removal from it; and the change in the aerodynamic drag and lift force of the streamlined bodies.

Numerical Analysis of Nanofluid on Stagnation Flow Past a Stretching Sheet in the Presence of Magnetohydrodynamics (MHD), Convective Heating and Double Diffusive Effects

The article provides a specific section of the model, which incorporates Soret-Dufour and convective heating effects, to emphasise the intricacies of the mathematical model for Nanofluid on stagnation flow towards a stretched sheet in the presence of a magnetic field. The revised governing equations in the form of linear ordinary differential equations were solved utilising shooting methods and a Runge-Kutta-Felhberg-integration technique. The plot used to explain the change in velocity, temperature, and concentration was based on a storey in which different characteristics appeared first on the graphs. Tables may also be used to analyse skin friction and the Nusselt and Sherwood values, both of which are essential in engineering. Following that, we will look at how the new method compares to previously known approaches in a few different situations. The main findings of this investigation are: the velocity profiles are increasing with increasing values of velocity ratio parameter and the reverse effect is observed in presence of Magnetic field parameter. The temperature profiles are rising with increasing the numerical values of Thermophoresis, Brownian motion, Diffusion thermo, Biot number parameters and the temperature profiles are decreasing with increasing values of Prandtl number. Also, the concentration profiles are rising with the increasing values of Thermophoresis, Thermal diffusion parameters and reverse effect is observed in case of Brownian motion parameter.

R-process Viable Outflows are Suppressed in Global Alpha-viscosity Models of Collapsar Disks

Collapsar disks have been proposed to be rich factories of heavy elements, but the major question of whether their outflows are neutron rich and could therefore represent significant sites of the rapid neutron-capture (r-) process or dominated by iron-group elements remains unresolved. We present the first global models of collapsars that start from a stellar progenitor and self-consistently describe the evolution of the disk, its composition, and its outflows in response to the imploding stellar mantle, using energy-dependent M1 neutrino transport and an α-viscosity to approximate turbulent angular-momentum transport. We find that a neutron-rich, neutrino-dominated accretion flow (NDAF) is established only marginally—either for short times or relatively low viscosities—because the disk tends to disintegrate into an advective disk already at relatively high mass-accretion rates, launching powerful outflows but preventing it from developing a hot, dense, and therefore neutron-rich core. Viscous outflows disrupt the star within ∼100 s with explosion energies close to that of hypernovae. If viscosity is ignored, a stable NDAF with disk mass of about 1 M ☉ is formed but is unable to release neutron-rich ejecta, while it produces a relatively mild explosion powered by a neutrino-driven wind blown off its surface. With ejecta electron fractions close to 0.5, all models presumably produce large amounts of 56Ni. Our results suggest that collapsar models based on the α-viscosity are inefficient r-process sites and that genuinely magnetohydrodynamic effects may be required to generate neutron-rich outflows. A relatively weak effective viscosity generated by magnetohydrodynamic turbulence would improve the prospects for obtaining neutron-rich ejecta.

Comparative study of two non-Newtonian fluids with bioconvective induced MHD flow in presence of multiple slips, heat source/sink and nonlinear thermal radiation

The present manuscript deals with bioconvective induced magnetohydrodynamic (MHD) flow of non-Newtonian fluids with simultaneous effects of multiple slips, heat source/sink, and nonlinear thermal radiation. Flows of Maxwell and Casson fluids are considered separately, but a single governing momentum conservation equation is constructed by combining these two flow models. Transformed governing equations are solved by MATLAB solver ‘bvp4c’. The objective of the current study is to check the comparative behaviour of two non-Newtonian fluids viz., Maxwell and Casson in presence of induced MHD effect with the bioconvective phenomenon and slip effect. The main findings reveal the growth of velocity and fall of microorganisms’ motile density with induced magnetic number. With higher values of Peclet number and microorganism concentration difference parameter, the microbe's motile density significantly reduces. The temperature hike is witnessed with heat generation/absorption, thermal radiation, and temperature ratio parameters. Also, for a fixed set of values of parameters the Casson fluid velocity is more prominent than the Maxwell fluid velocity and the scenario is the opposite for the motile density of microorganisms. Velocity increases, whereas motile density decreases with raising the amount of magnetic Prandtl number. Casson fluids have more velocity than Maxwell fluids, whereas the movement of the motile density of microorganisms is showing prominency for Maxwell fluids. The magnitude of surface drag and surface cooling rate are at a higher level for Casson fluid in comparison with Maxwell fluid. The motile density number enhances with the microorganism concentration difference parameter and Peclet number.

Dust coagulation and fragmentation in a collapsing cloud core and their influence on non-ideal magnetohydrodynamic effects

ABSTRACT We determine the time-evolution of the dust particle size distribution during the collapse of a cloud core, accounting for both dust coagulation and dust fragmentation, to investigate the influence of dust growth on non-ideal magnetohydrodynamic (MHD) effects. The density evolution of the collapsing core is given by a one-zone model. We assume two types of dust model: dust composed only of silicate (silicate dust) and dust with a surface covered by H2O ice (H2O ice dust). When only considering collisional coagulation, the non-ideal MHD effects are not effective in the high-density region for both the silicate and H2O ice dust cases. This is because dust coagulation reduces the abundance of small dust particles, resulting in less efficient adsorption of charged particles on the dust surface. For the silicate dust case, when collisional fragmentation is included, the non-ideal MHD effects do apply at a high density of nH > 1012 cm−3 because of the abundant production of small dust particles. On the other hand, for the H2O ice dust case, the production of small dust particles due to fragmentation is not efficient. Therefore, for the H2O ice dust case, non-ideal magnetohydrodynamic effects apply only in the range nH ≳ 1014 cm−3, even when collisional fragmentation is considered. Our results suggest that it is necessary to consider both dust collisional coagulation and fragmentation to activate non-ideal magnetohydrodynamic effects, which should play a significant role in the star and disc formation processes.

Significance of Ramped Temperature in the Dynamics of Unsteady Viscoelastic Fluid Subjected to Lorentz Force

Viscoelastic fluids, such as polymers, paints, and DNA suspensions, are almost everywhere and very useful in the industry. This article aims to study the significance of ramped temperature in the dynamics of viscoelastic fluid. Magnetohydrodynamic (MHD) effect is considered in the presence of Lorentz force. The flow is considered in a porous medium using generalized Darcy’s law. Heat transfers through convection, and the fluid near the plate takes heat in a ramped nature. Instead of the classical fluid model which has certain limitations, a generalized model is considered with fractional derivatives of the Atangana–Baleanu type. The well-known technique of Laplace transform was adopted to obtain the solutions which are displayed in various plots with detailed discussion analysis. From the graphical analysis, it is worth noting that the Atangana–Baleanu fractional model shows a good memory effect on the dynamics of the viscoelastic fluid as compared to its classical form.

Using Micropolar Nanofluid under a Magnetic Field to Enhance Natural Convective Heat Transfer around a Spherical Body

An analysis is discussed of the heat and mass transfer for micropolar nanofluid in presence of natural convection from a spherical body with magneto-hydrodynamic (MHD) effects. The constant wall temperature boundary condition is also studied. By employing proper similarity transformations, the governing equations are converted into a set of partial differential equations (PDEs) with the used boundary conditions, which can then be solved numerically via the efficient Keller-box implicit numerical finite difference method. The numerical results of impacts of the controlling parameters on heat transfer physical quantities have been presented, tabular and graphically, by MATLAB symbolic software. Comparisons of the current study results to previously published results show good agreement, indicating that our numerical computations are legitimate and accurate. Increasing nanoparticle volume fraction is observed to depress local skin friction, Nusselt number, and angular velocity while the reverse effects are observed for velocity and temperature.

MHD flow and heat transfer of a hybrid nanofluid past a nonlinear surface stretching/shrinking with effects of thermal radiation and suction

The essence of this study is to explore the nonlinearly stretching/shrinking hybrid nanofluid in terms of its steady flow and heat transfer with the effects of magnetohydrodynamics (MHD), thermal radiation, and suction. The governing partial differential equations are modified by similarity solution into nonlinear ordinary differential equations and solved numerically by bvp4c. The effects of profile on both velocity and temperature, the skin friction coefficient, and the Nusselt number were examined. It was discovered that dual solutions were present, and water has superior heat transfer performance compared to nanofluids and hybrid nanofluids. The thermal boundary layer thickness increases as magnetic and suction parameters increase. According to the stability analysis, first solution is steady, and second solution is unsteady.

Boosting photocatalytic activity through tuning electron spin states and external magnetic fields

Photocatalysis is considered as one of the most promising technologies to generate renewable energy and degrade environmental pollutants. Tremendous efforts have been made to improve photocatalytic efficiency. Among these, tuning spin polarization and introducing an external magnetic field are considered two promising strategies to boost photocatalytic performance. Herein this review highlights the recent breakthroughs through manipulating spin states and applying external magnetic fields for enhancing photocatalytic reactions. The relevant characterization techniques and fundamental mechanisms are summarized. Spin polarization states of photocatalysts have received considerable attention due to their unique roles, including inhibiting the recombination of photoexcited carriers owing to spin orientation constraint, enhancing the reaction product selectivity, and reducing the reaction barriers via optimizing the absorption energy and binding strength. As for the effects of external magnetic field on photocatalytic performance, we mainly discuss the separation enhancement of photoinduced carriers under static and time-varying magnetic fields and the magneto-hydrodynamic effect of charged particles. Lastly, the negative magnetoresistance effect is discussed due to the synergistic effects of the electron spin state and an external magnetic field. These discussions in this review may provide new insights into designing new semiconductors for boosting photocatalytic performance in internal and external magnetic fields.

Flow over a shrinking sheet containing hybrid nanoparticles with nonlinear thermal radiation and magnetohydrodynamic effects

This study aims to analyze the magnetohydrodynamic (MHD) and nonlinear thermal radiation effects on flow over a shrinking sheet containing hybrid nanoparticles. By adopting appropriate similarity variables, the partial differential equations are converted to the similarity equations of a particular form. Later, these equations are solved through the bvp4c function. The outcomes reveal that the heat transfer reduces as the nonlinear thermal radiation is introduced in the flow field by increasing the temperature ratio parameter. Physically, rising values of these parameters represent higher radiation heat energy is pumped into the flow field and lead to a growth in the fluid temperature. Consequently, it raises the thermal boundary layer and then reduces the heat transfer rate. However, increasing the magnetic parameter raises the friction factor which impulsively improves the heat transfer performance due to the rising strength of the Lorentz force. Besides, satisfactory suction strength is required to generate the solutions for the shrinking sheet. Lastly, the temporal stability analysis reveals the first solution is stable and thus physically reliable in the long run, whereas the second solution is unstable.

Exploring the dynamics of natural convective Prandtl fluid flow subjected to induced magnetic field

In the present study, Prandtl fluid flows naturally under the action of buoyancy in a vertical microchannel. The channel proliferates the fluid to the surrounding through small pores in the channel. Fluid flow properties are explored and heat transfer analysis is carried out theoretically via mathematical modeling using fluid dynamic conservative laws. Magnetohydrodynamics effect is also made a part of the study so that the induced magnetic field impact can be investigated. The mathematical form of the conservative laws leads to a differential system nonlinear in nature. The complexity of the mathematical system demands its solution to be carried out numerically. For this purpose, the finite difference-based Keller box method is utilized. Interpretation of the results is carried out in the form of graphs and tables of numerical values of the skin friction coefficient and the Nusselt number. The results show that the Prandtl number coupled with the suction velocity parameter results in an exponential growth in the heat transfer rate in Prandtl fluid. Graphical representations confirm the fact that skin friction coefficient peaks when the value of Hartmann number is minimum and that of Grashof number is maximum.

Dissipation of hydromagnetic waves in the viscous polytropic zone of the solar wind including FLR corrections, ohmic diffusion, and the Hall effect

ABSTRACT In the polytropic zone of the solar wind, we have used the generalized polytrope pressure laws to investigate the dissipation of hydromagnetic waves and pressure-anisotropy-driven fluid instabilities in magnetized viscous plasmas, including finite Larmor radius (FLR) corrections and non-ideal magnetohydrodynamic (MHD) effects. The modified dispersion properties have been analysed in the MHD and Chew–Goldberger–Low (CGL) limits for typical conditions of the solar wind and corona. The theoretical results are found to be in good agreement with the observational data, which shows that the MHD and CGL waves are dissipated due to viscous and ohmic diffusion. The FLR and Hall parameters show destabilizing and stabilizing influences, respectively, for the strong magnetic fields in the solar corona, and reversed effects in the case of weak magnetic fields in the solar wind. In the solar corona, the CGL wave dissipation achieves the required damping rate in the minimum time than the dissipation of the MHD waves. The damping time is mainly associated with the considered parameters and was found to be larger for the MHD wave dissipation than the CGL wave dissipation. The theoretical results successfully demonstrate the role of the considered parameters on the reverse and forward shock waves and instabilities as observed in the solar wind parameters versus heliolatitude graph using Ulysses observations for r = 5.41 au. The results are helpful to explore the possibilities of MHD waves and pressure-anisotropy-driven fluid instabilities in the polytropic zone of the solar wind that will probably be observed by the Parker Solar Probe (PSP) mission.

Experimental Investigations and Multi-Response Optimization of Dynamic Magnetic Field-Assisted Electrochemical Spark Drilling Using Grey Relational Analysis

Magnetic field-assisted electrochemical spark drilling (MA-ECSD) is a cost-effective triplex hybrid machining technique that has been developed to enhance the machining depth and surface roughness of insulated and hard-to-scribe materials. The study presented adopts a reformed approach for creation of dynamic magnetic field during drilling of Sodalime glass where a 34 AWG copper wire coiled electromagnet has been installed in the in-house designed and fabricated setup of MA-ECSD. The experimental plan is based on Box–Behnken design (BBD) of Response Surface Methodology (RSM) and significance of parameters is determined using ANOVA. Multi-objective optimization (MOO) is performed by applying Grey Relational Analysis (GRA). A noncontact optical profilometer measures the machining depths and surface roughness of drilled holes. The installed electromagnet generated dynamic magnetic field intensity (MFI) ranging between 0.00 and 0.18 Tesla. Preliminary experiments were conducted to select and set the range of input parameters. Significant effect of voltage, NaOH concentration and MFI on machining depth and surface roughness is found and optimal parameter settings obtained are 24[Formula: see text]V, 30[Formula: see text]wt% and 0.09 Tesla. Machining depth increased by about 13.03% with rise in voltage-NaOH concentration and surface roughness improved by 25.3% with elevation in voltage-MFI. Dynamic MFI generated from electromagnet helped in smooth motion of electrolyte in the fine space amidst cathode and glass slide due to magnetohydrodynamic effect (MHD) which resulted in enhanced machining depth and surface roughness. The experimental and predicted results obtained after confirmatory test are appreciable which is evident from SEM images and images obtained from Optical profilometer.

Magnetic-hybrid nanoparticles with stretching/shrinking cylinder in a suspension of MoS4 and copper nanoparticles

The main intent of the present study is to explore the varying fluid momentum and thermal energy characteristics of the laminar, steady, incompressible, two-dimensional, non-Newtonian pseudo plastic Williamson hybrid nanofluid over a stretching cylinder with variability in thermal conduction, suction, injection, heat generation and magneto hydrodynamic effects are considered. The mixture of Cu and MoS4 as nanoparticles in water as its base fluid is taken for this investigation as an hybrid nanofluid. The formulated governing PDEs are modified by employing with appropriate dimensionless transformations to get the non-linear ordinary differential equations. In accordance with the help of Runge-Kutta method of order four, shooting technique is implemented by making use of boundary value problem solver, bvp4c, which is accessible as an in-built function in MATLAB software for the numerical solution of the problem. The finding of this study are The values of Cf of the fluid grows with an increasing values of the physical parameters such as M and γ, whereas it is negatively influenced by λ. The values Nu of the Williamson hybrid Nano fluid has an increasing effect for the ascending entries of γ as well as Pr and has a reverse effect for the values of λ, M, β and ε of the fluid flow.

Artificial neural network joined with lattice Boltzmann method to study the effects of MHD on the slip velocity of FMWNT/water nanofluid flow inside a microchannel

Present research evaluates a wide range of methods to boost the performance of microchannel via ANN & lattice Boltzmann method (LBM). Hence Artificial Nueral Network method by Levenberg–Marquardt algorithm is applied to find all the data in the specific domain. LBM is developed to join with the artificial neural network (ANN) to study the effects of magneto hydro dynamic (MHD) on the slip velocity of FMWNT/water nanofluid flow inside a microchannel. Two methods are used to increase the efficiency of the cooling system. One is the effect of several fins (rectangular, triangular, and trapezoidal) and the second is the effect of magnetic field on thermo-hydraulic behavior. The magnetic field is caused to reduce the thermal boundary layer in the vicinity of the microchannels which means augmenting the performance by diminishing the vortexes. Finally, by rising the slip velocity coefficient from 0 to 0.1, the heat transfer saw a substantial enhancement of 6.1% and 5.4% in microchannel with rectangular at the lowest and highest amount of magnetic field, respectively. The original correlations regarding calculation of Nuave was obtained with R-square around 0.99.

Demonstration of RELAP5-3D for transient analysis of a dual coolant lead lithium fusion blanket concept

Our research aims to build a multiphysics framework for transient analysis of the Dual-Coolant Lead-Lithium (DCLL) blanket design of the proposed Fusion Nuclear Science Facility (FNSF) for all Anticipated Operational Occurrences (AOOs) using Reduced Order Models (ROMs). This paper presents an assessment of using RELAP5-3D for transient thermal-hydraulic blanket analysis of the DCLL design. Preliminary validation studies for the RELAP5-3D properties were conducted using a representative vertical flow loop model and a comparison study using experimental data from thermal convection corrosion loops at ORNL. These studies inspected the thermal hydraulic response of Lead-Lithium Eutectic (PbLi) systems within the RELAP5-3D code; mainly pressure drop and heat transfer, as compared to analytical calculations and experimental data. The Magnetohydrodynamic (MHD) pressure drop effect for liquid metal under the effects of a uniform magnetic field was implemented into our models using an equivalent forms loss coefficient based on the phasic momentum equations. We verified our implementation of MHD pressure drop within RELAP5-3D using a systematic approach consisting of two studies. Models were developed to perform comparison studies using experimental data from the Argonne Liquid metal EXperiment (ALEX) facility and the Magnetohydrodynamic PbLi Experiment (MaPLE) facility. Using the developed validation basis, we built a simplified DCLL channel model within RELAP5-3D, inspected MHD pressure drop and performed transient temperature analysis. The DCLL channel model used radial heating data from the International Thermonuclear Experimental Reactor (ITER) which was normalized to the FNSF design. A representative startup transient was performed using a relative power curve based on current PWR power ramp limits. This study demonstrated that RELAP5-3D ROMs are capable of accurate transient analysis of the DCLL blanket. We have since utilized MCNP to develop heating profiles based on the FNSF design and are working toward implementing them into our DCLL model.

Magnetohydrodynamic Effects on Third-Grade Fluid Flow and Heat Transfer with Darcy–Forchheimer Law over an Inclined Exponentially Stretching Sheet Embedded in a Porous Medium

The major aim of the current investigations is to study the magnetohydrodynamic effects on heat and mass transfer phenomena in third-grade fluid past an inclined exponentially stretching sheet fixed in a porous medium with Darcy–Forchheimer law influence. The constitutive equations compatible for heat and mass transportation in third-grade fluid in terms of partial differential equations are modeled. These partial differential equations are then converted to ordinary differential equations by using suitable similarity variables formulation. The transformed flow model is solved by using MATLAB built-in numerical solver bvp4c. Effects of pertinent parameters on physical properties that are velocity field, temperature field and mass concentration along with skin friction coefficient, Nusselt number and Sherwood number are demonstrated in graphs and tables. The impact of dimensionless numbers on the physical properties is analyzed and discussed with a physical view point at angle α=π/6 (inclined sheet). It is seen that as the third-grade fluid parameter (0.1≤β≤11) is increased, the velocity profile increases, but the temperature field and mass concentration are decreased. It is observed that as the permeability parameter (1≤K*≤11) is raised, the velocity distribution decreases and mass concentration increases. It is concluded from the results that owing to an increase in the local inertial coefficient (0.1≤Fr≤5), the velocity profile reduces but an increment in mass concentration is noted. It is concluded that by increasing values of magnetic field parameter (0.1≤M≤10) the velocity field is delineated and temperature field is elevated exactly according to the physics of magnetic field parameters. The present results are compared with already published results and it is observed that there is good agreement between them. This good agreement ensures the validation of accuracy of the results.

The impact of a magnetic field on electrode fouling during electrocoagulation

Electrocoagulation (EC) in water treatment encounters several challenges, such as electrode fouling and passivation, especially when the effluent has a complex composition, such as produced water in the oil and gas industry. In this study, the effectiveness of applying an external magnetic field during EC with aluminum anodes (Al-EC) or mild steel anodes (Fe-EC) was investigated for the first time for the removal of inorganic contaminants (including silica, calcium, magnesium, and sulfide) from synthetic and field samples of produced waters. For Al-EC, the presence of a magnetic field perpendicular to the electric field was found to enhance the treatment performance and mitigate the fouling formation on the electrode surface. Chronoamperometric investigations indicated that the application of MF in Al-EC enhances the current density and reduces the time to form a fouling layer on the electrode. In contrast, with Fe-EC, the presence of the magnetic field increased the rate of fouling on the electrodes. Potentiodynamic and kinetic investigations indicate that the magnetic field improves mass transfer via Kelvin force and magnetohydrodynamic (MHD) effects with no impact on the type of kinetic model, while the change in the spin states of the accumulated species has a negligible impact on reducing the fouling. The resistivity of the accumulated fouling layer (δRF) was found to reduce by around 23% due to a magnetic field of 0.158 T. Although increasing the strength of the applied MF increases the mass transfer, the effect is not linear. The results indicate that applying a magnetic field in Al-EC can be an effective method to mitigate fouling during water treatment.

An Experimental Complex for Researching High Velocity Magnetic Hydrodynamic Flows

A magnetohydrodynamic (MHD) stand based on a shock tube is described. A distinctive feature of this apparatus is the presence of a system for generating a magnetic field with an induction of up to 2.5 T and devices for ionization of the flow (electron gun, current generators), which makes it possible to solve a wide range of problems in magnetoplasma aerodynamics. The design features of the MHD test bench make it possible to simulate the MHD effect on the flow structure during flow around the investigated bodies under conditions of high-speed flight in the Earth’s atmosphere at the flow Mach numbers M = 6–12. The main experimental techniques used at the stand are considered. Examples of the results of the study of MHD effects obtained with this setup are presented.
