Analysis of Flow Past a Porous Rotating Disk with Thermo-Diffusion and Diffusion-Thermo with Convective Boundary Condition

Abstract

Analysis of flow past a porous rotating disk with thermo-diffusion and diffusion-thermo with convective boundary condition are studied and presented in rectangular form Mathematically. These equations are continuity, momentum, temperature and concentration which were reduced to nonlinear coupled ordinary differential equations from their PDE forms. The solution to these reduced equations were solved by introducing Adomian polynomials. The results were validated with the existing literatures and a good agreement was established. The parameters that occur in the solutions were varied on the fluid radial, tangential, axial velocities, temperature and concentration. Thermo-diffusion was found to enhance the fluid temperature while diffusion-thermo also boost the fluid concentration.
