摘要: 基于多重线涡模型(MLVM),本文建立了一种计算机时少、收敛性强的适用于大迎角涡流势流数值模拟的迭代算法。采用本文算法,首次得到了迎角直到60°的旋转体涡流的收敛解。计算出的空气动力数据与实验结果吻合。

Abstract: A robust iterative method suitable for the numerical simulation of vortex flows at high angles-of-attack is established based upon the multiple line-vortex model (MLVM). Converged solutions of vortical flows over bodies of revolution for angles of attack up to 60° are obtained. Calculated values of the aerodynamical loads on a tangent-ogive forebody compare well -with experimental data.

Key words: high angle of attack, vortical flows, iterative method.
