Abstract—Laser energy deposition method is a new and promising method as a flow control technique. In this study, this method is applied to three dimensional, turbulent, supersonic cavity flow which is a critical flow control problem. The application of the laser energy deposition is modeled by using a Gaussian temperature profile assuming the density within the spot is initially uniform. The effects of frequency, location and amount of the laser energy are investigated. At low frequency values, negligible reductions for sound pressure levels (SPL) are obtained. As the frequency is increased, SPL reductions up to 3 dB occur.
Index Terms—Active flow control, open cavity, supersonic flow, laser energy deposition.
