Abstract

Abstract

A mathematical model of air-water spraying cooling heat transfer in film boiling region is set up. With this model the heat flux and heat transfer coefficient can be calculated, when the air-water nozzle's water flux, droplet size and droplet velocity are given. The calculated results have a good agreement with the experimental datum.
