旋回をともなう自由乱流噴流
A Free Turbulent Jet with Swirl
土屋, 良明
A swirling turbulent jet of air is generated by flow issuing from a rotating pipe into a reservoir of motionless air. Experiment has been made of three cases of jets with different degrees of weak swirl. Each degree of swirl is obtained by changing the rotating speed of the pipe. Mean velocity magnitude and one component turbulence intensity are the main results. In contrast with the case of nonswirling jet, the result shows that the swirling jet spreads at a larger angle, entrenches reservoir air more rapidly, and consequently displays a more rapid reduction of the mean velocity as well as growth of the turbulence intensity.
