Abstract
The paper presents numerical results for non-Newtonian fluid confined horizontally between two rings. The outer ring has a circular shape, low temperature and rotates at a constant and uniform speed, while the inner ring has different shapes (circular, square and triangular), is constant and has a high temperature. This study aims to determine the method and the amount of heat transfer between the rings and under the influence of these factors: the rheological coefficient of the fluid, known as the power-law index, thermal buoyancy intensity, the rotation speed of the outer ring and the geometric shape of the inner ring. The experiment was performed numerically using the digital simulator ANSYS CFX. The results showed that the square shape of the ring reduced thermal activity compared to the circular shape. Furthermore, the effect of the power-law index on the fluid behavior is the same for all the shapes studied.
