Extract

Ventilated wall jets have recently received the attention of some investigators, motivated by its important applications in aircraft industry. In practice, the boundaries of the flow are more apt to be rough than smooth. The purpose of the present work is to study the effect of surface roughness on the mean and turbulence characteristics of ventilated wall jets. Experiments were performed with a two-dimensional turbulent jet flow over a smooth surface and over rough surfaces at different grades of sand roughness.
