Entropy generation and heat transport performance of a partially ionized viscoelastic tri-hybrid nanofluid flow over a convectively heated cylinder

A wide range of industrial applications where effective heat transport, fluid dynamics, and material adaptability are vital and can be addressed by the deployment of ternary hybrid nanofluids across an extensible cylinder. This work deals with entropy optimized flow and heat transport features of partially ionized and magnetically affected Prandtl fluid loaded with three nanomaterials drifting over a convectively heated cylinder. Three distinct nanomaterials (Al2O3,CuO,TiO2) are dispersed in order to enhance the heat performance rate of functional fluid. The ion and Hall slip effects, Joule heating, non-uniform heat source, and frictional heating are among the initial hypotheses in this computational analysis. The problem is presented quantitatively by taking the Tiwari-Das model to the basic equations. The Keller-Box framework is used to solve the nonlinear equations computationally. The findings reveal that enhancement in the Hall and ion slip effects diminish a rapid growth in entropy, while an opposite trend emerges for the Brinkman and magnetic parameter. The fluid motion is depressed by magnetic field intensity. The flow field and thermal transfer rate are enhanced by uplifting Prandtl first and curvature parameters. The system's irreversibility detracts with Brinkman number. A higher curvature parameter β results an elevated shear stresses and skin friction.

Hall and ion slip effects on the rheology of viscoelastic fluid – an application to polymers

The aim of present delivery is to address the peristaltic mechanism of a non-linear viscoelastic fluid in a compliant wall channel. Ion and Hall slip effects are considered. Heat transfer is analyzed by taking the effects of Ohmic and viscous dissipations. The problem is analyzed and formulated using regular perturbation method. Solutions of velocity, temperature, stream function and heat transfer coefficient are derived. Effects of various flow parameters on the flow quantities are examined through graphs.

Impact of hall and ion slip in a thermally stratified nanofluid flow comprising Cu and Al2O3 nanoparticles with nonuniform source/sink

Nanofluids play a pivotal role in the heat transport phenomenon and are essential in the cooling process of small gadgets like computer microchips and other related applications in microfluidics. Having such amazing applications of nanofluids, we intend to present a theoretical analysis of the thermally stratified 3D flow of nanofluid containing nano solid particles (Cu and Al2O3) over a nonlinear stretchable sheet with Ion and Hall slip effects. Moreover, the features of buoyance effect and non-uniform heat source/skin are also analyzed. For the study of numerically better results, Tawari and Das model is adopted here. For the conversion of the system of partial differential equations into ordinary differential equations, apposite transformations are engaged and are tackled by utilizing the bvp4c scheme of MATLAB software. The effects of dimensionless parameters on velocity and temperature profiles are depicted with the help of graphs. Additionally, the Skin friction coefficient and Nusselt number for the practical applications are examined in the tabular form. Verification of the current study by comparing it with an already published work in a special case is also a part of this study. Results show that the thermal performance of copper nanoparticles is more than alumina nanoparticles. An upsurge in the temperature of nanofluid is observed when the strength of the magnetic field is enhanced. However, the temperature of partially ionized nanofluid is significantly lowered because of the collisions of electrons and ions.
