Abstract: A flow field from a half confined slot jet to a moving surface is simulated. The simulation is based on the Reynolds stress turbulence model which is solved sequentially by the Simplic method. The simulation tells relationships between flow properties (such as shape of the flow field, turbulence intensity and local skin friction coefficient at the surface of the plate) and control parameters (such as jet angle and plate velocity). Further analysis of the relationships reveals that both the shape of the flow field and the distribution of the turbulence intensity become asymmetric when the jet angle is decreased or when the plate velocity is increased; the decrease of the jet angle or the increase of the plate velocity brings a secondary recirculation zone at one side of the flow field; the turbulence intensity near the wall and the local skin friction coefficient at the plate surface increase significantly when the plate speed reaches the twice of the inlet speed of the flow.
