Boiling nucleation on a very small film heater subjected to extremely rapid heating (Effect of ambient pressure on bubble formation by fluctuation nucleation)

摘要

The effect of ambient pressure on the dynamics of bubble formation in liquid heated rapidly to the limit of superheat is investigated by heating a fine film heater immersed in ethyl alcohol at a high rate of temperature rise up to 20*10~6 K/s. The heater surface temperature at boiling incipience increases with the increase of the rate of temperature rise and saturates at the rate higher than about 5*10~6K/s.
