FCAAP researchers are well known in the area of aeroacoustics and flow control. FCAAP houses anechoic wind tunnel and anechoic hot jet facility to study noise and flow control. Flow control is a rapidly emerging field of significant technological importance to the design and capability of a new generation of fluid systems, spawning major research initiatives in government, industry, and academic sectors. A variety of flow control techniques both active and passive have been developed and implemented in a range of applications involving flow separation, jet noise mitigation and flow optimization.
