POWER-LAW FLUID FLOW IN A T-SHAPED CHANNEL UNDER THE ACTION OF ASSIGNED PRESSURE DROP

Plane non-Newtonian incompressible fl uid fl ow in a T-shaped channel is considered. The effective viscosity is determined according to the Ostwald–de Waele law. The fl uid moves under the action of the given pressure drop in the boundary sections of the channel. The no-slip condition is fulfi lled on the solid walls. The problem is solved numerically by the control volume method with the use of the SIMPLE procedure. As a result of the investigation carried out, the characteristic fl ow regimes have been revealed. The infl uence of the basic parameters of the problem on the fl ow pattern has been demonstrated, and the dimensionless relations of fl ow characteristics have been constructed.
