HEMISPHERE CYLINDER AT INCIDENCE AT INTERMEDIATE TO HIGH REYNOLDS NUMBERS

摘要

Careful documentation of the development of leeward vortices and separation bubbles over a hemisphere-cylinder body at intermediate to high Reynolds numbers is presented. Flow visualization ,static pressure measurements, seven-hole probe anemometry, and laser Doppler velocimetry were employed to provide a complete picture of the flow at angles of attack of 0,10,20,and 30 deg. Composites of skin-friction lines and static pressure data are presented. Comparisons are made of the results obtained by a seven-hole probe and a fiber-optic laser Doppler velocimetry probe.
