Abstract:
A Turbulent Two Dimensional Flow Behind Perforated Plate Is Numerically Simulated And Compared With The Results Of Wind Tunnel Experiments From Literature [1]. Realizable K-? Of The Fluent Software Is Tested For The Normal Plates Of Porosities 0%, 10%, 20%, 30%, 40% And 50%, Using Which Mean Velocity, Surface Mean Pressure And Reattachment Lengths Were Predicted Inorder To Study The Fluid Interaction And The Size And Shape Of The Bubble. Realizable K-? Turbulent Model, Which Is An Eddy-Viscosity Turbulence Model, Performed Reasonably Well For The Thin Perforated Plate Under Study. For Perforation Greater Than 30%, The Simulation Showed That The Bubble Is Completely Swept Out As Proved By The Experiment.
