analysis of the second-grade fluid flow in a porous channel by cattaneo-christov and generalized fick’s theories

This attempt executes the combined heat mass transport features in steady mhd viscoelastic fluid flow through stretching walls of channel. the channel walls are considered to be porous. the analysis of heat transport is made by help cattaneo-christov heat diffusion formula while generalized fick’s theory is developed for study of mass transport. the system of partial differential expressions is changed into set of ordinary differential by introducing suitable variables. the homotopic scheme is introduced for solving the resultant equations and then validity of results are verified by various graphs. an extensive analysis has been performed for the influence of involved constraints on liquid velocity, concentration and temperature profiles. it is noted that the normal component of velocity decreases by increasing reynolds number while retards for increasing viscoelastic constraint. both temperature and concentration profiles enhanced by increasing combined parameter and reynolds number. the presence of thermal relaxation number and concentration relaxation number declines both temperature and concentration profiles, respectively.
