摘要
采用粘性流场边界元方法,对大冲角的翼栅绕流问题进行了研究。得到了速度场、内点的压力分布及翼栅边界面上的压力分布。为了提高计算精度,在对积分方程离散化时,加密了刻分网格,并且用混合单元方法对角点进行处理。计算方法简洁结果合理,适应性较强,显示了本文方法的优越性。
The problem of the flow around the big arch angle wing grid is studied by using viscous boundary element method. Velocity field and the distribution of pressure within inner points and pressure on boundary surface are obtained. In order to improve calculation accuracy, we encrypted division of grid and also used mingle element method in sharp section of boundary, when discretised integral equation. The calculation method is simple and precise. The result is rational. The adaptability is stronger. All these manifest advantage of boundary element method.
