A Numerical Study of the Bifurcation of Rectangular Synthetic Jets

Current Review on Numerical Simulation of Synthetic Jet (SJ) Cooling

“…Researchers frequently utilise the Semi-Implicit Method for Pressure Linked Equations (SIMPLE) technique to model incompressible flow because it works well for unsteady flow with tiny time steps.

“…Kumar et al, [29] investigates the mechanism of vortex creation and its bifurcation process. During the first axial switching, it has been noted that the vortex ring splits up close to the orifice exit and flows away from the centre of the SJ in the minor axis plane.…”

“…An earlier attempt had been made to explore the SJ effect through numerical simulation research. In order to simulate the moving diaphragm of the jet as a moving wall boundary, user-defined function (UDF) has been used [29,40,45,52,55]. The governing equations of continuity, momentum and energy based on URANS (Unsteady Reynolds Averaged Navier-Stokes) has been mostly used [26,46,48,49,52,55].…”

“…CFD software ANSYS Fluent with the Semi-Implicit Method for Pressure Linked Equations (SIMPLE) technique has been widely use among the researchers in order to simulate the incompressible flow. [16,25,29,40] In order to take into account turbulent and viscous effects, the k-omega SST model is mostly chosen to solve the mathematical model [10,16,19,25,26,40]. The turbulence model was used because it accurately depicts the flow in the vicinity of the wall and performs better when dealing with the large flow fluctuation [56].…”
