What is it about?
The investigation focuses on the effects of wall velocity slip on the solution of a viscous, laminar, incompressible channel flow subjected to small-scaled contraction and expansion of the weakly permeable walls. The study of such flow systems is often contextual for fluid transport in biological organisms.

Why is it important?
Lie symmetry analysis is used to reduce the number of independent variables from a system of partial differential equations. By using this symmetry analysis one can covert a complicated system of partial differential equations into a system of ordinary differential equations which is easier to solve.
