Electromagnetic steady motion of Casson fluid with heat and mass transfer through porous medium past a shrinking surface

Abstract

The motion of non-Newtonian fluid with heat and mass transfer through porous medium past a shrinking plate is discussed. The fluid obeys Casion model, heat generation, viscous dissipation, thermal diffusion and chemical reaction are taken in our considered. The motion is modulated mathematically by a system of non liner partial differential equations which describe the continuity, momentum, heat and mass equations. These system of non linear equations are transformed into ordinary differential equations by using a suitable transformations. These equations are solved numerically by using Mathematica package. The numerical distributions of the velocity, temperature and concentration are obtained as a functions of the physical parameters of the problem. Moreover the effects of these parameters on these solutions are discussed numerically and illustrated graphically through some figures. It is clear that these parameters play an important role to control the velocity, temperature and concentration of the fluid motion. It's found that the fluid velocity deceases with the increasing of electric parameter while it increases as the magnetic hartman parameter increases, these results is good agreament with the physical sitution. Also, the fluid temperature decreases and increases as the Prandtl number and Eckert number increases respeictively. At least the fluid concentration decreases with both of soret and schimdt numbers.

Entropy generation and nanoparticles Cu O effects on MHD peristaltic transport of micropolar non-Newtonian fluid with velocity and temperature slip conditions

“…The main aim of the present study is to minify entropy generation to obtain better results by restricting physical parameters of the problem. The dimensionless form of entropy generation can be exhibited mathematically as follows [3]:…”

“…The effect of micromagnetorotation (MMR) of a Hartmann micropolar flow on the heat transfer has been studied by Aslani and Sarris [2]. Eldabe et al [3] studied the motion of non-Newtonian fluid with mass and heat transfer a shrinking plate through porous medium. The importance of suction/injection for gravity modulation mixed convection is investigated due to an inclined sheet in micropolar fluid flow in the presence of thermal radiation and magnetic field by Ali et al [4].…”

“…But these figures also are excluded. Figure (16), illustrates the effect of the microorganisms concentration parameter on the concentration of microorganisms , it is found that the concentration of microorganisms increases with an increase in the microorganisms concentration parameter in the interval [0, 1.2), while it decreases with an increase in the microorganisms concentration parameter in the interval (1.2, 5]. Also, the concentration of microorganisms increases with an increase in the the velocity ratio B in the interval [0, 1.8), while it decreases with an increase in the velocity ratio B in the interval (1.8, 5].…”

“…The study of non-Newtonian fluids has attracted attention in recent years because of the use of many applications in different fields such as industry and engineering. The different types of non-Newtonian fluids are explained by many researchers [10]- [16]. Bhatti et al [17] invitegated the flow of Jeffrey fluid with small suspended particles through tapered duct with compliant walls in the presence of magnetic field, the fluid is electrically conducting, incompressible, irrotational with constant density.…”

Analytical Simulation of Heat and Mass Transmission in Casson Fluid Flow across a Stretching Surface

“…2-D mixed convection with heat transfer effect and concentration flow through a stretched layer was expended by Zeeshan et al [27]. Pal et al [28] studied the heat features with the non-Darcy flow in the existence of ohmic distraction, and El-Dabe et al [29] analyzed the non-Newtonian case and expanded the research of Pal and Mondal [28] for the shrinking surface.…”
