Abstract

Planar flow of shear-thinning fluid in a T-shaped channel is investigated assuming slip occurs along the wall. Motion of the fluid is caused by pressure difference between inlet/outlet boundaries. On the solid walls, two models of fluid interaction with solid walls are employed: no slip boundary condition and Navier slip boundary condition relating the wall shear stress to the slip velocity. The problem is solved numerically using a finite difference method based on the SIMPLE procedure. The parametric studies of the flow pattern depending on the main parameters of the problem have been performed. Dependences describing kinematic and dynamic characteristics of the flow have been shown.
