Shock Wave Solutions for Some Nonlinear Flow Models Arising in the Study of a Non-Newtonian Third Grade Fluid

Abstract EN

This study is based upon constructing a new class of closed-form shock wave solutions for some nonlinear problems arising in the study of a third grade fluid model.

The Lie symmetry reduction technique has been employed to reduce the governing nonlinear partial differential equations into nonlinear ordinary differential equations.

The reduced equations are then solved analytically, and the shock wave solutions are constructed.

The conditions on the physical parameters of the flow problems also fall out naturally in the process of the derivation of the solutions.
