EXPLORATORY EXPERIMENTS IN WATER ON STREAM-WISE VORTICES AND CROSSHATCHING OF THE SURFACE OF REENTRY BODIES

Abstract

A detailed description is given of the experimental results obtained on the stream-wise vortices using a water jet as an experimental device. Information on the vortices was obtained through a study of the stream-wise striations left in the coat on the models used by the outside flow. Striation counts were performed and the 'wavenumber' thus obtained is related to the flow parameters. The contention that the stream-wise vortices appear as a result of the outside curved flow becoming unstable is strongly supported.
