考虑了粘性不可压缩流体的Oseen螺旋流。严格分析了它们在雷诺数趋于无穷大时的极限行为,证明了内层宽度为O(R−1/2),其中为雷诺数。
Oseen’s spiral flows for viscous incompressible fluid are considered. Their limiting behavior as the Reynolds number tends to infinity is rigorously analyzed and the width of the interior layer is proved to be of O(R−1/2), whereR is the Reynolds number.
