Abstract

AbstractThe effect of multifluid flow on internal heat generation or absorption in a vertical channel in the presence of concentration is investigated in this paper. The fluids are incompressible in both regions, that is, Region‐I and Region‐II, and it is assumed the transport properties of fluid flow are constant. With the help of the analytical method, all the basic equations transformed into governing coupled nonlinear ordinary differential equations are solved, and the solutions obtained for fluid velocity, temperature, and concentration. These results are illustrated by plotting graphs and for various physical parameters. Here, we can control the results by means of the heat absorption coefficient, width ratio, and viscosity ratio.
