Abstract

A three-dimensional wall jet (3DWJ) is created when a jet of finite extension is ejected close to a wall, forming a complex and highly turbulent flow field, which spreads rapidly in the lateral direction. It is difficult to capture the 3DWJ in numerical simulations, especially the large lateral spreading rate, and as this flow case is of significant importance in many industrial applications, e.g. film cooling of gas turbine blades, a better understanding of the flow is required in order to improve its modeling.
