Résumé

New experimental data for critical heat flow rate under forced convection boiling of subcooled water are presented. The data are generalized over a wide range of parameters. In the region of transition from bubble to annular flow pattern, a nonmonotonous behavior of qcr was discovered. Preliminary data for porous coating influence on qcr are presented.
Experimental data on pressure drop, obtained in low-pressure range, make possible to forecast the region of reliable operation for cooling system.
Hypothesis on heat transfer mechanism for subcooled water forced convection boiling is given.
