Aiming at the problem of continuous control asymmetric forebody vortices a high angle attack in bi-stable regime, dual synthetic jet actuator embedded an ogive was designed. Alternating unsteady disturbance with varying degree asymmetrical flow fields near nozzles is generated by adjusting duty cycle drive signal actuator, specifically embodying time-averaged pattern velocity, vorticity, and turbulent kinetic energy. Experimental results show that within range relatively angles attack,...
Acceleration of objects in fluids widely exists biological propulsions and contains rich unsteady fluid mechanisms. In this paper, the instantaneous drag force on accelerating normal flat plates (circular, elliptical, square, rectangular plates) a wide range dimensionless acceleration (a*=16∼2) is measured, underlying mechanism for generation investigated. At first, we find that coefficient generally scales with square root a* when a*<1.0, coinciding scaling law given by Reijtenbagh...
