Abstract

In recent years, a promising approach to the control of wall bounded as well as free shear flows, using synthetic and pulsed jet actuators, has received a great deal of attention. A variety of impressive flow control results have been achieved experimentally by many researchers including the vectoring of conventional propulsive jets, modification of aerodynamic characteristics of bluff bodies, control of lift and drag of airfoils, reduction of skin-friction of a flat plate boundary layer, enhanced mixing in circular jets, and control of external as well as internal flow separation and of cavity oscillations. More recently, attempts have been made to numerically simulate some of these flowfields. Numerically several of the above mentioned flowfields have been simulated primarily by employing the Reynolds-Averaged Navier Stokes (RANS) equations with a turbulence model and a limited few by Direct Numerical Simulation (DNS). In simulations, both the simplified boundary conditions at the exit of the jet as well as the details of the cavity and lip have been included. In this paper, we describe the results of simulations for five different flowfields dealing with virtual aeroshaping, thrust-vectoring, interaction of a synthetic jet with a turbulent boundary layer and control of separation and cavity oscillations. These simulations have been performed using the RANS equations in conjunction with either one- or a two-equation turbulence model.
