基于涡量场的二维物体气动力计算

摘要

Two formulas to calculate the force of the object in the limited flow field according to vorticity field were proposed.In the flow field numerically simulated by FLUENT,the forces of a flat plate with Re number 1000 was calculated by the two formulas.The results from different methods are close.The proposed two formulas are simpler than Noca's FLUX and MOMENTUM equations.%提出了在有限流场区域中根据涡量场计算二维物体气动力的两个公式.在FLUENT数值模拟得到的流场中,运用提出的两个公式,计算了雷诺数为1000的二维无厚度平板的气动力.按照不同方法计算得到的结果接近.提出的两个公式比Noca的FLUX和MOMENTUM公式在形式上简单,便于使用.
