FLOW impingement of a supersonic jet on a solid surface produces a highly turbulent and complex flowfield with a multiple shock systems and viscous-inviscid interactions [1,2]. Many examples of such a flowfield can be found in engineering applications such as: the launch of a rocket, takeoff and landing of a short takeoff and vertical landing (STOVL) aircraft and the exhaust of an aircraft on a carrier deck impinging on a deflector plate. Very often this unsteady flowfield has a detrimental effect on the performance of the aerodynamic system where such flows occur; making its control highly desirable. A better understanding of the complex flowfield associated with impinging jets is therefore needed to design efficient control systems which can mitigate its effects on the aircraft/vehicles. As an example, STOVL aircraft during hover produce highly oscillatory impinging jets on the landing surface [3].
