Critical heat flux modeling in water pool boiling during power transients

Critical heat flux modeling in water pool boiling during power transients

This article suggests a method of the determination of main parameters and dynamic characteristics of heat transfer crisis on a surface of fast heated wall. The new physical models describing process of transition from nucleate to film boiling are presented. The results of transient critical heat fl...

Zusammenfassung:This article suggests a method of the determination of main parameters and dynamic characteristics of heat transfer crisis on a surface of fast heated wall. The new physical models describing process of transition from nucleate to film boiling are presented. The results of transient critical heat flux modeling are compared with the experimental data for saturated water pool boiling under atmospheric pressure.
