Heat transfer during propagation of boiling fronts in superheated liquids.

Author(s) : FAUSER J., MITROVIC J.

Summary

Propagation velocities of two-phase fronts, which develop during the transition from single-phase convection of superheated liquids into a stable mode of boiling, and the instationary heat flux in the front region are determined experimentally. The experiments are carried out with pure liquids (ethanol, water, heptane and R11). The outer surface of a horizontally arranged copper tube (diameter 18 millimeters) served as heating surface. The measurements are undertaken along isobars at pressures of 10 à 350 kilopascals and stationary heat fluxes up to 40 kilowatts/m2. Phenomenon are carefully described, for heptane, ethanol, R11 and water.
