Swirling annular impinging jets with hysteretic behavior

Original language description

This paper is focused on an annular impinging jet with hysteretic behavior and possibility to control the phenomenon by means of jet swirling. An experimental study was performed with air as the working fluid using flow visualization, hot wire anemometryand wall pressure measurement. The bistability and hysteresis were confirmed and two different flowfield patterns were revealed under the same boundary conditions. It was found that weak swirling (S = 0.03) decreases the tendency to bistability and hysteretic behavior. The Reynolds number effect was also found: the bistability and hysteresis were identified only at Re < 3000.
