It is an established phenomenon that bubbles can be stabilized in a vertically vibrating liquid column. The effect of bubble stabilization on the rate of pool boiling heat transfer is experimentally investigated. With the liquid and heating surface vibrating as a unit, the data indicates a decrease of up to 12 percent in the temperature difference necessary for a given heat flux within the range of frequencies from 200 to 300 cps. The experimental results and comparison with results of previous investigators show that the effect is unique and not due simply to the vibrations per se.
