Title: Exact Solutions of nonNewtonian Fluid Flows with Prescribed
Vorticity
Abstract
During the past decade, there has been substantial interest in flows of
viscoelastic liquids due to the occurrence of these fluids in industrial
processes. The equations of motion of a nonNewtonian secondgrade fluid
flow are highly nonlinear partial differential equations. For this reason, we
cannot find the general solution. Thus, there exist only a limited number of
exact solutions. Due to the complexity of the equations, inverse methods
become attractive in the study of nonNewtonian fluids. In this lecture, we
study the steady incompressible viscous nonNewtonian secondgrade fluid
flows in which the vorticity is proportional to the stream function perturbed
by a uniform stream.
