Acoustically enhanced boiling heat transfer [PDF]

open access: yes2007 13th International Workshop on Thermal Investigation of ICs and Systems (THERMINIC), 2007
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
