The flow boiling CHF multi-model correlations derived by Fukuda et al., and it was made clear that the flow boiling CHF data for outlet subcoolings, pressures and flow velocities measured by many researchers were divided into some regions for the outlet subcooling as a parameter of outlet pressures. In this research deals with as an extension of previous work, the useful flow boiling heat transfer with the critical heat flux for outlet subcooling and pressure for the heated tubes with the ratio of tube length to diameter values and the flowing water with flow velocities. The correlation curves with three constants versus flow velocities as a parameter of the test tube diameters are derived from corresponding experimental data. The calculated value derived from the corresponding critical heat flux correlations with constants obtained, compared with corresponding datum points to confirm for reasonable accuracy.

Fukuda等人推导的流动沸腾CHF多模型关联式，指出了许多研究者所测得的出口过冷度、压力和流速的流动沸腾CHF数据，都是以出口过冷度作为出口压力参数而划分的区域。本文在前人工作的基础上，研究了加热管的有效流动沸腾换热与出口过冷度和压力的临界热流密度与管长径比的关系，以及流动水的有效流动沸腾换热与流速的关系。根据相应的实验数据，导出了三个常数与流速的相关曲线。根据得到的临界热流密度关联式和常数计算出相应的计算值，并与相应的基准点进行比较，以确认合理的精度。
