摘要：

Based on experiments a new law is proposed for the vortex shedding from a circular cylinder which describes in a consistent way the Strouhal-Reynolds-number dependency as Sr=Sr*+m/root Re from the beginning of the vortex shedding at Re=47 up to the laminar-tubulent transition of the cylinder boundary layer at Re>2x10(5). The various vortex shedding processes, occurring with increasing Reynolds number, are described by different coefficients Sr* and m. (C) 1998 American Institute of Physics.
