Abstract
To study heat transfer between a flow of droplets and heated metallic surfaces, a special rig has been fabricated and experiments have been carried out with varied wetting density, size and velocity of the droplets. For the temperature of maximum heat removal and the corresponding heat transfer rate empirical relations have been obtained which agree well with an approximate theoretical description of the process. Physical justification is given for the thermal hysteresis observed in the heating-cooling cycle.
