Effusion cooling is based on a row or a grid of injection holes. The behavior of the cooling jet after leaving the hole and within the boundary layer above the wall is investigated. Therefore a foreign gas (Helium, Argon) was injected as coolant into a cross flow and a pitot probe was used to get gas samples out of the boundary layer to measure the coolant gas fraction. The measured concentration was empirically systematized by comparative data analysis. As a result of the data evaluation, the hole’s angle was found to have a minor influence on the mean coolant concentration. An angle of about 30° is a good compromise between production effort and cooling efficiency. Also coolant fluids with a low molar mass and high specific heat capacity should be preferred because of their low impact on the boundary layer. Show less
