THESIS JET AEROACOUSTICS

Previous and ongoing measurements to investigate the flow field and acoustics of jets have included: The faculty members and students that conduct research in aeroacoustics use both experimental and computational methods. Aeroacoustics Aeroacoustics is the study of the generation of sound by unsteady air flow. Staff Aerospace Engineering Staff. The unsteady turbulent flow field can also be simulated with numerical solutions of the full equations of motion. Aeroacoustics is the study of the generation of sound by unsteady air flow. These calculations are very computationally intensive, but can be performed on the computer clusters available in the department.

Our students are consistently among the most highly recruited by industry, government, and graduate schools nationwide. In the former case, knowledge of the average flow allows the radiated noise to be estimated using analytical methods. Computational aeroacoustics involves the numerical simulation of the unsteady flow and the noise it produces. 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. 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. Previous and Ongoing Measurements Previous and ongoing measurements to investigate the flow field and acoustics of jets have included:

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.

Undergraduate What is Aerospace Engineering? These calculations are very computationally intensive, but can be performed on the computer clusters available in the department.

The department is built upon the fundamentals of academic integrity, innovation in research, and commitment to the advancement of industry. Recent Experimental Research 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 aeroacoustkcs heated jet.

The sound could be generated by jets, fans, rotor blades, and any devices that force the air into unsteady motion. Predictions can be based on steady or unsteady flow calculations. Computational Aeroacoustics Computational aeroacoustics involves the numerical simulation of the unsteady flow and the noise it produces. 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.
