The PIV Measurements of Time-Averaged Parameters of the Synthetic Jet for Different Orifice Shapes

Popis výsledku v původním jazyce

In the present study, the flow fields generated by a synthetic jet (SJ) were investigated with particle image velocimetry (PIV). The SJ time-averaged parameters, such as velocity, turbulent kinetic energy (TKE), and vorticity, were compared by using the Reynolds number (Re = 5000) and dimensionless stroke length (L-0 = 2;10). Three different orifice shapes with the same equivalent diameter were used: circle, square, and slot. The flow fields of the investigated parameters were presented and discussed at a distance from the orifice x/d b= 10, and the difference in radial and axial profiles were compared. The impact of the orifice shape and dimensionless stroke length on the investigated parameters was discussed.
