Abstract
An incompressible flow in a porous channel with expanding or contacting walls in the presence of a transverse magnetic field is considered. Using similarity transformations, the governing equations are reduced to the nonlinear ordinary differential equations. The exact similar solutions for the different cases of the expansion ratio and the Hartmann number are obtained with a singular perturbation method, and the associated behavior is discussed in detail.

Moderate-to-large injection and suction driven channel flows with expanding or contracting walls

TL;DR: In this article, the Navier-Stokes equations are reduced to a single, nonlinear, ordinary differential equation, and the resulting equation is then solved both numerically and asymptotically, using perturbations in the crossflow Reynolds number R.
