摘要：A turbulent two dimensional flow behind perforated plate is numerically simulated and compared with theresults of wind tunnel experiments from literature [1]. Realizable k-ε of the Fluent software is tested for the normalplates of porosities 0%, 10%, 20%, 30%, 40% and 50%, using which mean velocity, surface mean pressure andreattachment lengths were predicted inorder to study the fluid interaction and the size and shape of the bubble.Realizable k-ε turbulent model, which is an eddy-viscosity turbulence model, performed reasonably well for the thinperforated plate under study. For perforation greater than 30%, the simulation showed that the bubble is completelyswept out as proved by the experiment.
