NUMERICAL AND EXPERIMENTAL INVESTIGATION OF BEVELED TRAILING EDGE FLOW FIELDS

The characteristics of flow past beveled trailing edges attached to flat plates have been investigated numerically and experimentally.The test models used in the present study were two 2D blunt-faced flat plates having asymmetric beveled trailing edges of angles 27° and 60°.The numerical simulation results display an asymmetric wake behind the 27° beveled trailing edge and von karmen street vortices behind the 60° beveled trailing edge.The flow visualization using cavitation technique showed the same observations of the numerical simulation.Therefore,it is obvious that the trailing edge geometry has a pronounced effect on the wake development and vortex shedding.Also,it is concluded that the cavitation phenomenon can be used as a visualization technique at high flow velocities.
