Abstract

The effect of vibration on the heat transfer rate in the pool boiling of water was investigated using a horizontal 0.0315 cm diameter nickel-aluminium wire vibrated in a vertical plane. The frequency of vibration was varied from 0-124 Hz, the amplitude from 0-0.2032 cm, and the heat flux from 0-7.25×105 W/m2. The experimental data from both the stationary and the vibrating surfaces are correlated by a modification of the Rohsenow pool boiling equation. It has been found that the Rohsenow constant dependent on the type of solid/liquid combination assumes one value for the high flux boiling and another different value for lower flux boiling processes.
