Type of article: Article
Summary
In a systematic experimental study the behaviour of a periodically precessing jet was compared to that of the corresponding steady inlined jet. The precessing motion is that of self-sustained unsteadiness which is a consequence of an axisymmetric "Coanda-like" effect. The flow field is characterized by mean flow, turbulence and frequency data from hot wire measurements. The heat transfer data, in terms of Nusselt numbers, were determined on a specially designed heat transfer plate in the plane of jet impingement.
