Study of forced turbulent flow of a non-Newtonian fluid in convergent channels

Abstract

his study analyzes numerically the behavior of permanent, incompressible, forced, and turbulent flow in convergent ducts, in horizontal and vertical configurations. The fluid uses is non-Newtonian and obeys to power law model. the resolution of this bi-dimensional problem was carried out by Ansys Fluent 19.2. The objective was to understand the dynamic and thermal behavior at different Reynolds numbers and provide insights for practical applications in petroleum engineering. The analysis of velocity profiles revealed proportionality among the Reynolds number and velocity at the outlet of the ducts. The heat exchange between the fluid and the wall is neglected, influenced by forced convection. The fluid keeps its temperature from the inlet to the outlet of the channel
