Numerical study of flow separation control over a circular hump using synthetic jet actuators
نویسندگان
چکیده
This study deals with the wall resolved Unsteady Reynolds-Averaged Navier–Stokes (URANS) simulation of boundary layer flow separation over a circular hump model and its active control. An array Synthetic Jet Actuators (SJAs) is implemented in to introduce train vortex rings into control separation. The OpenFOAM solver used numerically simulate analyze fluid using k– ω shear stress transport model. Hot wire anemometry particle image velocimetry measurements are carried out evaluate accuracy URANS technique as well effectiveness SJAs by comparing numerical predictions experimental data. time-averaged results good agreement demonstrate successful application delay interactions vortical structures separated flow. three-dimensional also reveals that near coherent (streamwise spanwise vortices) responsible for components. can be better understand performance further improve future actuator configurations.

Effects of a synthetic jet acting on a separated flow over a hump
The effects of an oscillatory zero-net-mass-flux jet (i.e. synthetic jet) acting on a separated flow over a hump are investigated in terms of two actuation parameters – actuator position and forcing frequency. By considering the vorticity flux balance and introducing a centroid of vorticity production over the hump surface, lift and drag acting on the hump can be expressed as a function of this...

Abstract A new second order theoretical model of the combined interaction of externally applied electric and magnetic fields and viscous incompressible fluid flows has been rewritten as a system of first order partial differential equations. The system was solved using a least-squares finite element model on an unstructured grid. The numerical algorithm is very stable and accurate. The accuracy...
