On the spread of rectangular jets
Abstract
Results are presented of some characteristic features of turbulent free jets issuing from rectangular exits having different geometries and small aspect ratios. Emphasis is placed on the measurement in the flow field near the exit. The measured quantities include mean velocity, mean temperature and stream-wise turbulence intensity. It is found that the growth and decay of the spanwise saddle-backed profile for temperature is different from that for velocity, and that the streamwise turbulence intensity distribution shows a remarkable change according to aspect ratio, exit shape and exit velocity.
