Résumé

An experimental study of nucleate boiling from a transparent heater 2 surface to Freon 113 is presented in which heat flux (11,500 - 129,400 W/m2 ), subcooling (0 - 30°C) and acceleration (1 - 100 g's) were varied. The temperature of the heater surface and the temperature distribution in the adjacent liquid were measured and the active site density, the average population density, the bubble frequency and the maximum bubble diameter were determined by means of high speed photography. The contributions of natural convection and nucleate boiling were separated. Two components of the heat transfer associated with each bubble, the latent heat transport and the transport associated with the induced convection action of the bubbles were computed as functions of heat flux, subcooling and acceleration.
