NUMERICAL AND EXPERIMENTAL STUDY OF FLOW AROUND TWO PLATES HAVING ASYMMETRIC BEVELED TRAILING EDGE

The flow around two plates having asymmetric beveled trailing edge placed side-by-side in a uniform stream were investigated both numerically and experimentally. Two plates with spacing ratio of 1.0 and beveled trailing edge of angle 20o were tested at Reynolds numbers equal to 3.97×104. The numerical simulation results displayed that the flow separates on one plate beveled trailing edge surface. The vortex formation and shedding from this plate led to deflecting the flow toward the other plate and consequently the wake behind the plates showed an asymmetric development. The photographs obtained from the flow visualization confirmed the numerical results concerning the flow separation and vortex formation. It was also found that the computed pressure distribution on the two plate surfaces was different, particularly on the beveled trailing edge surfaces and on the flat sides.
