Abstract

During the last twenty years a considerable amount of work has been done in order to understand buffeting and the mechanism of the separated flow that causes it. In these investigations the results have either not been clear or they contain some unknown interaction between the indicating apparatus and the flow in the wake. In the present paper one type of the formerly observed flow configurations is investigated by using a properly compensated hot wire anemometer. This technique exhibits some of the results previously obtained but with greater significance and some added phenomena.
