Abstract : The behavior of bubbles nucleating from a glass cavity was studied using high speed photography. Water and ethanol were used with varying amounts of cavity heat at several subatomospheric pressures. Bubble growth, departure diameter, and frequency were related to the fluid used, cavity heat, operating pressure and local convection currents. At low pressures, the departure diameter was studied for dynamic effects. The frequency-departure diameter product was observed for increasing bubble frequency.
