Effect of chemical reaction on unsteady heat and mass transfer in a vertical wavy channel with oscillatory flux and heat source

摘要

In the present article, we study the effect of chemical reaction on unsteady heat and mass transfer in a vertical wavy channel with oscillatory flux and heat source. The governing partial differential equations are transformed into a system of ordinary differential equations by non-dimensional procedure and are then solved by using regular perturbation technique. The velocity, temperature and concentration profiles are analyzed graphically for different variations in the parameters. The physical interpretation to these expressions is examined through graphs and tables for the shear stress and rate of heat transfer coefficients at the vertical channel walls.
