Abstract

Slightly heated swirling jets have been investigated experimentally in order to determine the effect of swirl degree on the mean and turbulent flow pattern. In particular, it has been shown that the swirl action strongly intensifies the turbulent momentum and heat transport processes in the close vicinity of the jet outlet and tends to quench them further downstream.
