S.P. : The Proceedings of the Symposium on Mechanics for Space Flight 1988}, month = {Mar}, note = {Separated flows around pitching wing sections are simulated numerically by a discrete vortex method combined with a panal method. The potential flows around wing sections is expressed by vortex sheets and separated shear layers are expressed by discrete vortices. In the calculation a separation point is determined by solving boundary layer equation. The strength of shed vortex is estimated using local velocity near separation poing. Also modification for the estimation of pressure coefficients around wing section are proposed. The estimated pressure distributions show good agreements with experimental results. Also separated flows around pitching airfoils are simulated. A hysteresis of lift of airfoil at dynamic stall is obtained., 資料番号: SA0033625000}, pages = {11--20}, title = {Numerical Simulation of Separated Flow around Two-Dimensional Wing Section by a Discrete Vortex Method}, volume = {9}, year = {1989} }
