An experimental study is carried out to investigate flow field characteristics of unconfined and confined twin slot jets impinging on an inclined surface. Pressure distributions on the impingement and confinement surface were obtained for Reynolds number of 15000, nozzle-to-plate spacing (H/W) in the range of 1-18 and inclination angle of impingement plate (alpha) in the range of 0 degrees-42 degrees. The effects of nozzle-to-plate spacing, inclination angle and flow confinement on the pressure distributions were examined. In the case of confined jet, subatmospheric regions occur on both impingement and confinement surfaces and their strength decreases with increasing nozzle-to-plate spacing. There is no evidence of the subatmospheric region in unconfined jet. Distinct peaks occurred on primary stagnation points of impinging plates is turned to single peak with increasing angle of inclination.
