Thermal control of electronic devices has been an active research area of heat transfer technologies. The impetus is straightforward: decreasing the temperature of a component increases its performance as well as its reliability. In the present study, a single microchip is placed in a 2D channel. A simple triangular cavity configuration is used to investigate the effectiveness of a synthetic jet for its thermal management. The study presents altered main channel flow results for various synthetic jet configurations and different membrane oscillation frequencies. The effect is that synthetic jet enhances mixing by imparting momentum to the channel flow thus manipulating the temperature field in a positive manner. Computations carried out for both continuum and slip flow regimes.
