RESEARCH INTERESTS:

Research interests focus on rotorcraft and aircraft aeroacoustics, computational aeroacoustics, fluid mechanics, computational fluid dynamics, and high performance computing.  Specific areas of research include rotor source noise prediction, prediction and characterization of rotorcraft noise in maneuvering flight, prediction of landing gear noise and other types of airframe noise. Recent research activities include the development of the rotorcraft noise prediction code PSU-WOPWOP which is able to predict noise from a rotorcraft with multiple rotors in both steady and maneuvering flight; prediction of noise generation and propagation from wind turbines; development of a component based landing gear noise prediction system; and investigation of soot combustion in underexpanded jet plume flows.
