| Research Abstract |
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.
