Synthetic jet enhancement of natural convection and pool boiling heat transfer in an enclosure, filled with a
dielectric, electronic cooling liquid (FC-72) was studied. The jet was produced by a diaphragm-driven actuator that was operated at resonance and produced planar, submerged liquid jets that impinged upon a flat foil heater and spread laterally along its surface. The induced convective thermal transport from the heated surface yielded nearly a four fold improvement in heat transfer over unassisted natural convection. The highest enhancement of pool boiling was observed near boiling incipience, with the synthetic jet producing an earlier transition to nucleate boiling than encountered in a quiescent pool.
