Abstract

The problem of generation of steady streaming by an oscillating circular cylinder is considered. For the case of a finite oscillation frequency, the asymptotic expansion of the solution in terms of a small oscillation amplitude is constructed. In the leading steady term the two possible regimes of secondary streaming are analyzed. The fluid pumping effect of secondary streaming is studied. Energy efficient pumping regime is determined. The limits of applicability of high-frequency asymptotic solutions are established.

由圆柱体的低振幅振荡产生的稳定流

摘要

考虑了振荡圆柱体产生稳定流的问题。对于有限振荡频率的情况，根据小振荡幅度构造解的渐近展开。在领先的稳定项中，分析了二次流的两种可能的制度。研究了二次流的流体泵送效果。确定了节能泵送方式。建立了高频渐近解的适用范围。
