On the Development of an Efficient Wake Survey System 951990
A recursive algorithm has been developed to automatically generate multi-grid meshed wind tunnel wake surveys. Using near-real-time processing of 7-hole probe pressure data to obtain velocity components, the local circulation in the flow was computed and used to determine the grid spacing. This results in a significant reduction in the number of sample stations per survey. Results from a recent test at the 7 by 10 Foot Wind Tunnel at NASA /Ames Research Center are presented.
