Краткое описание

Steady state film boiling experiments have been performed on a vertical flat plate, 0.305 m in height, and 3.175 cm wide with forced convective upflow of subcooled water at atmospheric pressure. Data have been obtained for mass flux ranging from 0 to 700 kg/m2s and inlet subcooling ranging from 0 to 25 °C. In addition to the wall heat transfer coefficient, vapor film thickness, temperature profile in the film, and interface to liquid heat transfer rate were measured. The wall heat transfer coefficient data have been correlated with an empirical model that incorporates the effects of all the relevant independent parameters on flow film boiling heat transfer. This model predicts the experimental data to within ±12%.
