Abstract

Starting flows around a circular cylinder undergoing uniform acceleration from rest are studied numerically and experimentally for Rea = 350,1310, 2170, 5000. The calculation and experiment are in good agreement. Evolution with time of the flow structure and the effects of Rea are studied,and some new phenomena are revealed. Comparisons are made with the flows of impulsively started cylinders.
