声学强化沸腾传热
Acoustically Enhanced Boiling Heat Transfer
摘要：
利用声场提高平板沸腾传热表面的临界热流密度。这种增加是蒸汽泡上的声学效应的结果。实验研究了声场对刚性加热壁面附近汽泡的影响。工作包括一种新型的加热器的建设，用于产生一个单一的蒸汽气泡的规定尺寸和在规定的位置上的flatboiling表面更好地研究一个单独的蒸汽气泡的反应的声场。工作还包括从单泡加热器的校准铜加热器用于量化CHF的改善的结果的应用。
英文摘要：
An acoustic field is used to increase the critical heat flux (CHF) of a flat-boiling-heat-transfer surface. The increase is a result of the acoustic effects on the vapor bubbles. Experiments are performed to explore the effects of an acoustic field on vapor bubbles in the vicinity of a rigid-heated wall. Work includes the construction of a novel heater used to produce a single vapor bubble of a prescribed size and at a prescribed location on a flatboiling surface for better study of an individual vapor bubble's reaction to the acoustic field. Work also includes application of the results from the single-bubble heater to a calibrated-copper heater used for quantifying the improvements in CHF.
