... are employed to predict the flow state and capture the liquid-gas interface. The model was validated by comparing with the experimental data. The results show that the microjet violently impinges on the heated wall after the bubble collapses completely. In the meantime, the thickness of the thermal boundary...

...Eric A. Browne; Gregory J. Michna; Michael K. Jensen; Yoav Peles The heat transfer performance of two microjet arrays was investigated using degassed deionized water and air. The inline jet arrays had diameters of 54 μ m and 112 μ m , a spacing of 250 μ m , a standoff of 200 μ m ( S / d = 2.2...

... an order-of-magnitude less than that predicted by correlations developed from macroscale jet data, and the dependence on the Reynolds number is much weaker than expected. Further investigation of microjet heat transfer is needed to explain the deviation from expected behavior. 16 01 2009 04 05...
