Enhancing the Heat Transfer Due to Hybrid Nanofluid Flow Induced by a Porous Rotary Disk with Hall and Heat Generation Effects

Naif Abdulaziz M. Alkuhayli

Summary: A study is conducted on the hybrid-nanofluid flow induced by the rotation of a circular porous disk to enhance heat transfer rate. The effects of Hall and Ohmic heating as well as heat generation/absorption on flow behavior and heat transfer are investigated. The physical problem is simplified to nonlinear partial differential equations using conservation laws and solved using the Shooting Method. Results show that wall suction significantly affects velocity components, while enhanced Hartman number influences radial and axial velocities. The effects of parametric variations on temperature depend on heat generation/absorption.

Heat and mass transfer analysis for MHD bioconvection peristaltic motion of Powell-Eyring nanofluid with variable thermal characteristics

J. Iqbal et al.

Summary: This study investigates the effects of mass and heat transfer on the bioconvective peristaltic transport of Powell-Eyring nanofluid under a curved channel with a magnetic field. Various factors such as Ohmic heating, motile microorganisms, thermal radiation, variable properties, Brownian and thermophoresis motion are taken into account. The results show that the stability of nanoparticles and heat transfer are enhanced by the presence of motile microorganisms. The model is simplified using lubricant approximations and numerical solutions are obtained using NDSolve in Mathematica.

Entropy generation analysis for magnetized peristaltic movement of nanofluid through a non-uniform asymmetric channel with variable thermal conductivity

F. M. Abbasi et al.

Summary: This study investigates the impact of entropy generation on MHD peristaltic flow of nanofluid through a non-uniform asymmetric channel, taking into account its rheological aspects. The results show that a strong magnetic field reduces the Bejan number and entropy generation is lower for flow through a divergent channel.

Viscous dissipation effect on forced convective transport of nanofluids in an asymmetrically heated parallel-plate microchannel

A. K. W. Loh et al.

Summary: This study investigates the effects of viscous dissipation on the transport of Alumina-water nanofluids in an asymmetrically heated microchannel, taking into account Brownian motion and thermophoresis mechanism. It is found that viscous dissipation shifts the concentration and temperature distribution, leading to changes in thermal conductivity and viscosity. The increase in nanoparticle bulk concentration and the Brownian and Thermophoretic diffusivity ratio highlight the competition between enhanced thermal diffusion and hindered heat convection. Viscous dissipation also has a pronounced effect on particle migration and entropy generation.

Mixed convection and thermal radiation effect on MHD peristaltic motion of Powell-Eyring nanofluid

Bilal Ahmed et al.

Summary: This study investigates the influence of mixed convection, Hall current, and magnetic field on the peristaltic motion of Powell-Eyring nanofluid in a symmetric channel, considering factors such as viscous dissipation, thermal radiation, Brownian motion, and thermophoresis. Numerical solutions show that higher magnetic fields lead to an increase in temperature, while Hall effects exhibit the opposite trend.
