Abstract : This report results from a contract tasking University of Manchester as follows: The investigation will be conducted in the University of Manchester hypersonic blowdown wind tunnel facility (HSST) at Mach no. 4 to 6. All experimental tasks will utilize the following experimental techniques: i) Particle Image Velocimetry (PIV) and laser sheet; ii) Intensity-based in-house developed Pressure Sensitive Paint (PSP) imaging system; iii) Pressure tapings; iv) Pitot pressure and total temperature probes; v) Oil flow; and vi) High-speed phase-locked schlieren photography and double exposure holographic interferometry. Task 1: Plasma and non-plasma (PnP) jet system and model design, and performance tests. Task 2: Transverse non-plasma jet interaction tests: Investigation of the physics of transverse non-plasma jet interactions and determination of penetration distance of the jet into the cross-flow and separation lateral spreading. Task 3: Active control of transverse jet interaction using localized arc filament plasma actuators (LAFPA): 3.1 Investigation of the physics of transverse jet interactions with LAFPA and determination of penetration distance of the jet into the cross-flow and separation lateral spreading; 3.2 Evaluation of the benefits of LAFPA system to enhance mixing of the jet with the cross flow fluid through modification of instabilities. Task 4: Transverse plasma jet interaction tests: Investigation of the physics of transverse plasma jet interactions and determination of penetration distance of the jet into the cross-flow and separation lateral spreading. Milestones: Year 1: Transverse non-plasma jet interaction studies and baseline studies on localized arc filament plasma actuator (LAFPA) system design. Year 2: Active control of transverse jet interaction using localized arc filament plasma actuators (LAFPA). Year 3: Transverse plasma jet interaction studies.
