Critical Heat Fluxes of Subcooled Water Flow Boiling in Short Vertical Tube (Part 2. Inlet CHF Correlation)

摘要

CHF correlation against inlet subcoolings was given in non-dimensional form based on the experimental data performed in Part 1 of this paper. The correlation can describe not only the CHFs obtained in this work at the inlet pressure of 800 kPa but also the authors' published CHFs data (1284 points) for the wide range of P{sub}(in)=159 kPa to 1 MPa, d=3 to 12 mm, L=33 to 149 mm, ΔT{sub}(sub,in)=10 to 151 K and u=4.0 to 13.3 m/s within ±15 % difference for 50 K≤ΔT{sub}(sub,in)≤151 K.
