Influence of synthetic jet in crossflow configuration on heat transfer enhancement

Abstract

A two-dimensional computational model was developed to investigate the effect of synthetic jet interaction with crossflow in channel on the cooling of heat wall. A range of parametric studies by varying membrane oscillating amplitudes and inlet velocities of channel was conducted. The resulting complex, conjugate heat dissipation was analysed. The synthetic jet interacts with the channel flow and gives rise to heat dissipation enhancement at the heated wall. The upstream heat transfer deteriorates in the jet hole, and the heat transfer in the downstream region has improved.

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.

“…Additionally, an increase in SJ cooling performance may not be possible for vibration amplitude increments greater than 0.6mm. The effect of SJ interaction with crossflow in channel on the cooling of heat wall is investigated by Xiang et al, [33]. The interaction of the SJ with the channel flow enhances heat dissipation at the heated wall.…”
