Abstract

In this study, the main objective is to preliminary investigate the mechanism of flow structure and pressure losses reduction in turning diffusers before and after installing turning baffles. For this investigation two baffles were installed in the turning diffuser. CFD code FLUENT was used to simulate and obtain the results. From the resulting outputs, before baffles were installed, there was a flow separation at the inner wall of the turning diffuser and the velocity distribution was not evenly distributed. After the installation of baffles, there was an improvement in reducing flow separation at the inner wall of diffuser and the velocity was evenly more distributed. However, there was a significant pressure loss while having baffles in the system as much as 2.5.
