Abstract
This paper describes an investigation of the local heat/mass transfer for rotating impingement/effusion cooling. A study was conducted of parameters such as jet orientation and surface geometry. An experiment using the naphthalene sublimation method provided the local heat/mass transfer coefficients on the effusion plate. The heat/mass transfer distributions for the axial orientation were similar to those for the stationary cases, while the trailing orientation produced different Sherwood number features, with divided high Sh regions and one low Sh region around the stagnation area. The concave surface provided better and more uniform heat/mass transfer than the flat surface.
