Research Description: Experimental fluid dynamics focusing on fundamental fluid flow problems that have practical applications. Specific areas include: turbulent shear flows, separating flows, high-speed jets and the associated problems of compressible mixing and noise. Study of microflows and their use in controlling large-scale flows. Development and use of non intrusive flow diagnostics, especially optical methods for complex flows. Over the last few years his research has in large part focused on active flow and noise control, such as the control of supersonic jets, cavity flows and flow separation and in the related area of development and implementation of actuators, especially micro-fluidic actuators, for flow & noise control applications.
PIRE Project Description:
The aim of this research is to better understand the fluid dynamics of the massively separated flowfield that occurs around most vehicles and is responsible for a substantial portion of the aerodynamic drag . Armed with an improved understanding, we then apply flow control schemes, primarily using actuators developed at the Advanced Aero-Propulsion Laboratory (AAPL) at FSU to efficiently control this flow with the aim of minimizing separation and aerodynamic drag.
Here, we examine the flow and noise properties of high speed jets, mainly in the transonic to supersonic regime in order to examine and correlate the flow field features/properties that are primarily responsible for jet noise. Two configurations are examined, the impinging jet and the free jet for cold as well as hot flows. Through correlated flow &noise measurements, we hope to develop reduced order or physical models that captures the jet aeroacoustics, identify optimal location and actuator properties for noise control and ultimately implement high-bandwidth actuators that can effectively control jet noise.
