摘要
建立了二维浅水流动的旋涡诱导速度公式,在已知旋涡场和胀量场时,由该表达式可确定流动速度场. 对比分析了二维浅水流动中的涡运动与可压缩流动中涡运动的异同点.
A formula is deduced for the velocity induced by the vortices in two-dimensional shallow water flows and it is used to correct the Biot-Savart law. The dynamic characteristics of vortex motion in two dimensional shallow water flows are analyzed and the comparison of vortex motion in shallow water flows with the vortex motion in compressible flows are made.
