摘要

The accurate prediction of CHF in pool and forced convection boiling is of importance in a wide variety of process equipment, A great volume of experimental and analytical studies on the CHF have been conducted by many researchers during the last several decades. State-of-the-art overview of the phenomena and prediction models and correlations are available in the literature (Collier and Thome, 1994; Chang and Baek, 1997a). Generally, the CHF under forced convective conditions is classified into two groups: departure from nucleate boiling (DNB) at subcooled or low-quality regions and liquid film dryout (LFD) at high quality. The physical mechanism of the LFD is relatively well understood. However, the detailed aspects of the DNB mechanism have not been clearly understood (Weisman, 1992; Katto, 1994; Bricard and Shouyri, 1995; Chang and Baek, 1997b).
