Two expressions for the Nusselt criterion have been formulated by applying self-similarity methods to the laminar free-convection film boiling on a vertical surface having the finite length, which is submerged into the large volume of arbitrary subcooled liquid. The expressions apply Nusselt criterion to the conditions of continuous transition from film boiling in saturated liquid to the strongly subcooled liquid in order to determine heat transfer between the heated surface and interphase boundary, and heat transfer from this boundary into the volume of liquid; the accompanying radiative heat transfer is taken into account. The hierarchy of different self-similarities is presented.

Transfer Coefficients

Natural convection film boiling heat transfer of saturated liquids on an isothermal vertical surface is investigated both experimentally and theoretically. Local heat transfer coefficients are obtained at steady-state conditions on a 6.3-cm-wide and 10.3-cm-high heated surface which was machined from a large block of copper. Effectively isothermal surface conditions are achieved even for wall superheats up to 450 K. Experiments conducted with water at 1 atm pressure show that predictions from existing theoretical models are inadequate and a detailed consideration of the liquid-vapor interface behavior is required. Still and motion pictures of the vapor film are taken and data on vapor film thickness, interfacial wave behavior, and bubble detachment characteristics are obtained to build an analytical model for predicting film boiling heat transfer. This time-dependent model based on laminar flow in the film incorporates the effects of both large-scale and small-scale waves. Results from analysis are compared with experimental data.
