Effect of Chemical Reaction on Mass Transfer due to a Permeable Rotating Heated Disk

Abstract

An unsteady three dimensional flow in an incompressible viscous, chemically reacting fluid mixture due to a permeable rotating heated disk is studied by taking into account the effects of magnetic field, ohmic heating, viscous dissipation, chemical reaction and suction or injection. The system of nonlinear partial differential equations governing the flow, heat and mass transfer is reduced to a system of nonlinear ordinary differential equations by using similarity transformations. The resulting system of ordinary coupled nonlinear differential equations is solved numerically by bvp4c and solutions are presented graphically. All numerical calculations are done with respect to air at 20 0 C (Pr = 0.71) in presence of Hydrogen (Sc = 0.22). Numerical values of the local skin frictions and the rate of heat and mass transfers are shown in tables.

Use of the repeated integral transformation method to describe the transport of solute in soil

“…Previously, researchers [ 6 , 22 , 24 , [126] , [127] , [128] ] investigated the effect of chemical reaction on heat or mass transfer using different but related forms of chemical reaction parameters. To cite a few, Ravindran et al [ 22 ] used a chemical reaction parameter , where and were respectively, defined as chemical reaction rate and kinematic viscosity.…”

“…To cite a few, Ravindran et al [ 22 ] used a chemical reaction parameter , where and were respectively, defined as chemical reaction rate and kinematic viscosity. Similarly, Sharma and Konwar [ 126 ] considered a chemical reaction parameter , where is the uniform angular velocity. In its simplicity, Gao et al [ 6 ] used a constant linear mass transfer coefficient as a chemical reaction parameter.…”

Computer-extended series solution for laminar flow between a fixed impermeable disk and a porous rotating disk

“…The unsteady magnetohydrodynamics (MHD) squeezing flow between two parallel disks is investigated by Azimi and Riazi (2015). Many researchers (Sharma and Konwar, 2015; Shahmohamadi and Mohammadpour, 2014; Srinivas et al , 2016) have also discussed unsteady fluid flow and heat transfer over permeable rotating disk, rotating porous disk and infinite rotating disk under different boundary conditions.…”

Radiation Effects in Flow through Porous Medium over a Rotating Disk with Variable Fluid Properties

“…The unsteady magnetohydrodynamic (MHD) squeezing flow between two parallel disks (which is filled with nanofluid) is considered by Azimi and Riazi [14]; they have used Galerkin optimal homotopy asymptotic method (GOHAM) to solve the problem. Several researchers [15][16][17] have also investigated unsteady fluid flow and heat transfer over permeable rotating disk, rotating porous disk, and infinite rotating disk under different boundary conditions.…”
