FLOW VISUALIZATION IN WIND TUNNELS USING INDICATORS

This AGARDograph describes various flow visualization techniques in current use in British wind tunnel practice which are not dealt with fully elsewhere. Emphasis is on such of these techniques that have been developed during recent years - particularly those devised for the understanding of separated flows. These include two of the most valuable methods for investigating three-dimensional flow; namely, the vapour screen and surface oil flow techniques. Other techniques described are various techniques for locating boundary-layer transition, and smoke techniques for use in lowspeed wind tunnels. Included in the AGARDograph are many References, and also an extensive Bibliography covering the complete range of indicator techniques.
