Nonlinear trend of subcooled water flow boiling CHFs versus outlet subcooling for flow velocities at outlet pressures in tubes flowing subcooled water was studied using existing database based on the corresponding correlations extending the new correlations with different mechanisms recently developed for the nonlinear trend of CHF in through tubes with wide ranges of inside diameter, and length-to-diameter ratio for wide ranges of flow velocities, outlet pressure and outlet subcooling. The object of this paper is to clarify if the CHF correlation mentioned above can be extended to apply to the previously existing flow boiling CHF data obtained for the test sections such as a heated metal strip in a channel with rectangular cross section, and heated tubes with various diameters and lengths under wide ranges of conditions.
