THESIS JET AEROACOUSTICS

The unsteady turbulent flow field can also be simulated with numerical solutions of the full equations of motion. This capability is used to examine the effect of forward flight on the noise generated by jet flows or the effect of wind on the noise produced by the jets on a STOVL Short takeoff and vertical landing vehicle. Ongoing projects include the simulation of the flow in jets with noise reduction devices and the calculation of the unsteady pressure loading on an aft deck downstream of a rectangular nozzle. Predictions can be based on steady or unsteady flow calculations. Recent experimental research has included the development of a noise reduction methodology for supersonic heated jets, such as those found on tactical fighter aircraft, and measurements of the temperature on a ground plane below a vertical impinging heated jet.

In the former case, knowledge of the average flow allows the radiated noise to be estimated using analytical methods. The unsteady turbulent flow field can also be simulated with numerical solutions of the full equations of motion. These calculations are very computationally intensive, but can be performed on the computer clusters available in the department.

The faculty members and students that conduct research in aeroacoustics use both aeroacousticx and computational methods.
