| Research Abstract |
In order to enhance the fuel mixing in a scramjet engine, a new method of fuel mixing is suggested. This method is based on the method in which cavity-induced flow oscillation is utilized. The geometry of the cavity is improved so that the three-dimensional flow field is produced. This three-dimensional flow advantages the mixing enhancement. In order to simulate the fuel injection, the nitrogen gas which contains a small amount of acetone is injected into the supersonic flow. The mixing of the injected gas is visualized by the laser-induce acetone fluorescence. As a result, the mixing enhancement by the improved cavity is found to be stronger than that by the conventional rectangular cavity.
