Pressure driven laminar flow of a power-law fluid in a T-channel

Planar flow of a non-Newtonian fluid in a T-channel is investigated. The viscosity is determined by the Ostwald-de Waele power law. Motion of the fluid is caused by pressure drop given in boundary sections of the T-channel. On the solid walls, the no slip boundary condition is used. The problem is n...

Description
Summary:Planar flow of a non-Newtonian fluid in a T-channel is investigated. The viscosity is determined by the Ostwald-de Waele power law. Motion of the fluid is caused by pressure drop given in boundary sections of the T-channel. On the solid walls, the no slip boundary condition is used. The problem is numerically solved with using a finite difference method based on the SIMPLE procedure. As a result of this study, characteristic flow regimes have been found. Influence of main parameters on the flow pattern has been demonstrated. Criteria dependences describing basic characteristics of the flow under conditions of the present work have been shown.
