Numerical Investigation of The Flow in Fractal Type Bifurcation and Trifurcation Systems with Different Features

Abstract

In this study, CFD and mathematical analyses were performed on straight pipe, double branched and triple branched pipe models. In the straight pipe model, it was observed that the velocity was maximum at the center and decreased towards the wall. While the velocity distribution was homogeneous at the inlet section, the velocity profile changed as the flow developed. In the double branched and triple branched pipe models, it was determined that the velocity decreased in the separation regions and vortex formations caused a decrease in velocity and an increase in pressure. The fact that the side branches were of the same diameter and in the same plane kept the differences in the velocity distribution to a minimum. The results showed that fractal flow systems with small aspect ratios provided less pressure loss.
