| Abstract | ||||
| The goal of the present study is to investigate the flow through an asymmetric low aspect ratio planar diffuser. The flow which is fully developed channel flow inlet conditions is both experimentally investigated and computed using commercial cfd code, fluent. Rng k- model is used as a turbulence model and standard wall function is used. The questions about the two-dimensionality of the flow are investigated. The Reynolds number of diffuser inlet flow is 3.5 x 105 based on the centerline velocity and the channel height. Flow is visualized to get insight view of the flow map in the diffuser. | ||||
