Flow control via Synthetic Jets (SJs) is experimentally studied for a separated flow over a back-facing ramp in wind tunnel tests at height-based Reynolds number of 10700 using planar Particle Image Velocimetry. Two cases, i.e., either without control (baseline) or controlled by means of SJs, have been investigated. The effectiveness of the control is achieved through a momentum addition of cμ = 3.0 × 10^(-3) at a reduced frequency F+ = 0.34. Under the SJs control, the separated region undergoes a reduction in length of 62% of that observed for the baseline case.

Abstract
Flow control via Synthetic Jets (SJs) is experimentally studied for a separated flow over a back-facing ramp in wind tunnel tests at height-based Reynolds number of 10700 using planar Particle Image Velocimetry. Two cases, i.e., either without control (baseline) or controlled by means of SJs, have been investigated. The effectiveness of the control is achieved through a momentum addition of cμ = 3.0 × 10^(-3) at a reduced frequency F+ = 0.34. Under the SJs control, the separated region undergoes a reduction in length of 62% of that observed for the baseline case.| File | Dimensione | Formato | |
