Effects of Forchheimer, MHD and Radiation Absorption for Chemically Reacting Unsteady Dusty Viscoelastic Fluid Couette Flow in an Irregular Channel

In this work, a study which contributes toward the combined effects of Forchheimer, MHD, and radiation absorption for a laminar two-dimensional chemically reacting unsteady dusty viscoelastic fluid in an irregular channel is considered. The physical model demands nonlinear coupled partial differential equations under the wavy channel conditions. Computational results are obtained to understand the characteristics of velocity, temperature, and concentration for various physical parameters involved in the model using a novel analytical perturbation method with combined Soret and Forchheimer number. Obtained results are well matched with the physical model and found to be a good agreement with the earlier works for a particular case.
