In this study the parameters of jet impingement cooling system were determined and possible effects were observed. Single row of jet impinging to a flat target surface in a nozzle guide vane of a gas turbine engine were simulated due to the operating conditions. In the scope of geometry; metal which was in contact with the air at 1500 K and 800 kPa was cooled via the air at 500 K and 400 kPa. For specified problem; channel height, distance between jets and Reynolds number were chosen as parameters affecting cooling performance. Three different channel height value as 2D, 3D, 4D; three different distance between jets value as 4D, 5D, 6D and three different Re number value as 4000, 5000, 10000 were used for the solutions. As a result of 27 different combinations best cooling configuration was determined as 2D(channel height), 4D (jet spacing) with Re number as 10000.
