WebThe Strouhal number which is calculated by Kuwahara’s method for a plate at an incidence of 60” placed in a uniform free stream is 22-36 yo smaller than that observed experimentally, when the distance a, between the locations of the nascent vortices and the edges of the plate is taken as aJ(2a) = 0*0125,2a being the half-height of the plate. WebThe transition phenomena in the wake of an inclined at plate at angle of attack 25 degrees are investigated numerically. The Reynolds number, based on the free-stream velocity, plate width and kinematic viscosity, between 275 and 800 has been considered. The Strouhal number versus Reynolds number curves were plotted and compared with two ...
