Abstract
Based on visualizing and tracking the flow by use of smoke stream and surface pressure measurement, the entire process of the flow behavior around a slender ogival cylinder at various angles of attack from 0° to 90° is observed and analyzed systematically. It is found that in the experiment, at various angles of attack, the structure of the flowfield around the slender body is different and the range of attack angle involved by the evolvement process is small. The evolvement process can mainly be finished in a small range of attack angle.
