In this research, the practical correlation and flow regime model is proposed on the basis of heat transfer coefficient analyzed from boiling heat transfer experiment, under temperature control, using following experimental parameter: mass flux in upstream [kgm^<-2>s^<-1>] and sub-cooled temperature in upstream [K]. As the result, it is indicated that forced convective boiling heat transfer coefficient under high mass flux condition show higher value than that of pool boiling. Correlation for heat transfer coefficient and experimental value agree well in DNB region and is demonstrated adequacy and practicability. This flow regime model is presupposed as high concentration droplet flow. And it is also noted that the gravity and centrifugal force affect to the heat transfer coefficient in some experimental condition for horizontal straight or curve tube.
