Abstract
This paper presents new experimental data on the film boiling of ethanol on a copper ball at pressures up to 0.8 MPa and subcooling temperatures of 53–166 K. An analysis is made of the reasons for the discrepancy between the experimental data on the heat transfer in stable film boiling of subcooled liquid and the results of calculations with the use of the approximate model developed earlier by us and its correction has been made. A semi-empirical computing equation is proposed that describes all experimental data on the film boiling of nonaqueous liquids subcooled to 170 K at pressures of 0.1–1.0 MPa.
