| Abstract: | Performance characteristics of S-shaped rectangular diffusers have been investigated using CFD. The characteristics have been obtained for 15°/15°, 22.5°/22.5°, 30°/30°, 45°/45° and 90°/90° diffusers for constant circular center line length of 600 mm having an aspect ratio of 2, 4 and 6 at inlet. It is observed that as the curvature increases, the uniformity of flow at the outlet reduces, the cross flow velocities at the outlet increase and the coefficient of pressure recovery decreases. The effect of aspect ratio on the performance characteristics of these diffusers is also similar, i.e. reduction in aspect ratio reduces flow uniformity and pressure recovery. |
