Abstract

This paper presents a systematic study of the effect of the Reynolds number on the fluid dynamics and turbulence statistics of pulsed jets impinging on a flat surface. In a previous study there was evidence suggesting that the Reynolds number might have a different effect on pulsating jets compared to steady jets. The pulsed jets are compared with their steady counterpart at a similar Reynolds number. The Reynolds numbers considered in this study correspond approximately to Re = 4000, Re = 6250 and Re = 10000. All the other factors that affect the flow field are kept constant; H/d = 3, St = 0.25 and d=30.5mm.
