Краткое описание

The present investigation aims to computationally analyse the effect of various geometric parameters on the flow and performance characteristics of S-shaped diffusers. S-shaped diffusers are encountered in various engineering applications such as aircraft intakes, turbomachinary passages, diffusing bends of piping systems. The geometric parameters namely; aspect ratio, area ratio, centerline length and shape of the diffusers are varied in the present computational investigation. Varying centerline length of the diffuser increased the total pressure loss coefficient. Rectangular diffuser with area ratio of four performs better with higher static pressure rise and lower total pressure loss.
