Nonlinear stretched flow of a radiative MHD Prandtl fluid with entropy generation and mixed convection

Frontiers in Physics, 2023
This paper examines the analysis of entropy generation in the flow of an MHD Prandtl fluid over a nonlinear stretching sheet. Heat transfer is developed through a convectively heated sheet.

Numerical study of heat and mass transfer enhancement in Prandtl fluid MHD flow using Cattaneo-Christov heat flux theory

Case Studies in Thermal Engineering, 2022
Heat and mass transfer have numerous industrial applications. The classical heat and mass transfer laws (Fourier and Fick laws) do not predict thermal and solute relaxation time phenomena.

Heat transfer analysis of generalized second-grade fluid with exponential heating and thermal heat flux

Scientific Reports, 2023
The aim of present work is to apply the Caputo–Fabrizio fractional derivative in the constitutive equations of heat transfer. Natural convection flow of an unsteady second grade fluid over a vertical plate with exponential heating is discussed.

Effect of natural heat convection on fractional MHD second-grade fluid in an infinite vertically oscillating cylinder with Hankel transform

Heliyon, 2023
In this paper, we studied the effect of a magnetic field on the non-isothermal second-grade fluid confined in a vertically oscillating cylinder. The flow solution is magnetized using the perpendicular magnetic field.

Prandtl number of lattice Bhatnagar–Gross–Krook fluid [PDF]

Physics of Fluids, 1995
The lattice Bhatnagar–Gross–Krook modeled fluid has an unchangeable unit Prandtl number. A simple method is introduced in this report to formulate a flexible Prandtl number for the modeled fluid. The effectiveness of this method was demonstrated by numerical simulation of the Couette flow.
