Flow over a sphere
WebMar 29, 2006 · Vortex shedding from spheres has been studied in the Reynolds number range 400 < Re < 5 × 10 6.At low Reynolds numbers, i.e. up to Re = 3 × 10 3, the values of the Strouhal number as a function of Reynolds number measured by Möller (1938) have been confirmed using water flow.The lower critical Reynolds number, first reported by … WebFeb 2, 2011 · Pressure decreases over the front half of the sphere from the stagnation point onwards, thus having a stabilizing effect on the boundary layer, which remains laminar up to about Re d = 5·10 5. Beyond the minimum pressure point on the sphere surface, the boundary layer is subjected to an adverse pressure gradient and the fluid decelerates.
