Abstract:

An attempt was made to map the density field in a fin-flat plate junction three-dimensionally using holographic interferometry. The investigation has extended previous density studies to include, for the first time, interferometric fringe information obtained through a transparent model in supersonic flow. Feasibility of the method was demonstrated. The factors which are thought to have limited the success of the experiment include vibration of the model, fluctuations of the tunnel flow and size of the model in relation to the size of the wind tunnel test section. Schlieren photography was used to look through and around the model and to verify that the same flow was established as was reported by other investigators.
