To establish confidence in existing theoretical models and to provide justification for their use in engineering practice, experiments have been performed to obtain heat fluxes for subcooled film boiling on the surface of a preheated test specimen exposed to a water wall jet. Comparisons between the experimental data and theoretical results are generally favorable, with the largest discrepancy corresponding to underprediction of the data by approximately 40% at locations close to the quench front, where some liquid-solid contact is likely. Much better agreement is achieved in zones of developed film boiling, where the model assumptions are more appropriate.
