抄録

Two dimensional vortex shedding behind an inclined flat plate is simulated by point vortex arrays separating from the both edges. The strengths of point vortices are determined from the Kutta condition. The flow round the body is impulsively started from rest with the angle of attack 89°, 75°, 60°, 45° or 30°. The calculated values of drag coefficients in the case of the angle of attack 89° have their marked peak initially and decrease gradually to the values of about one and remain at this stage for some time and then suddenly increase to the values of 4 or 5 and finally oscillate between about 2 and 4. This final stage corresponds to the flow with vortex shedding of Karman’s type. Similar results are obtained in other cases.
