Flow Classification of the Under-Expanded Super Sonic Jet Impinging on a Flat Plate

Numerical Simulation of Supersonic Jet Impingement on Inclined Plate

“…These numerical studies could provide explanations of the complex shock interactions. Nakai 9,10 , et al conducted an important experimental investigation of supersonic jet impingement on inclined plate with different inclination angles, pressure ratios and nozzle plate distances. They have measured detailed pressure distribution in the plate surface with pressure sensitive paints (PSP) and used Schlieren methods to visualize the flow field.…”

“…McIlroy and Fujii 11 have numerically simulated the experimental condition of Nakai 9,10 , et al for pressure ratios of 4.5, 7.4 and 10.1 and presented a detailed flow structure of this complex problem. Three dimensional Navier Stokes equations with Baldwin Lomax turbulence model 12 were solved by discretizing the inviscid terms with a second order accurate simple highresolution upwind scheme (SHUS) 13 and viscous terms with a second order central differencing.…”

“…In the present work, the experimental conditions of Nakai 9,10 , et al are simulated numerically using commercial CFD software 16 for different pressure ratios, inclination angles and the nozzle exit to impingement plate distance. The computed flow profiles are compared with the experimental value to demonstrate the capability of CFD codes with industry standard physical models.…”

Mach Number Effect on Flowfield Over a Delta Wing in Supersonic Region

“…PSP technique [11][12][13][14] is an optical method that enables measurement of surface pressure distribution over a model basing on oxygen and thermal quenching of luminescent molecules. Here, PSP measurement system based on blue LED and Ruthenium (II) complex is used (Fig.4).…”

Flow Field Analysis of Jet Impinging on an Inclined Flat Plate at High Plate Angles

“…Recently, new techniques of surface pressure or temperature measurement system called Pressure/Temperature Sensitive Paint [PSP/TSP] are often used among the field of aerospace [4][5][6] . Nakai et al 7 proposed use of PSP for measurement of the surface pressure on the plate. PSP bases on the oxygen quenching of the photoluminescence and can easily obtain the surface pressure distribution as an image with much higher spatial resolution compared to the conventional point-wise measuring system such as pressure taps.…”
