Summary

THE CRITICAL HEAT FLUX (CHF) CONDITION WAS EXPERIMENTALLY DETERMINED FOR SUBCOOLED FLOW BOILING FROM AN ARRAY OF SIMULATED MICROELECTRONIC DEVICES ON ONE WALL OF A VERTICAL RECTANGULAR PASSAGE. USING R113 AS THE COOLANT, THE CHF CONDITION WAS DETERMINED FOR FLUSH AND SLIGHTLY PROTRUDING HEATED ELEMENTS. AT MODERATE FLOW VELOCITIES, THE CRITICAL HEAT FLUX PREDICTED BY A PROPOSED CORRELATION FOR SUBCOOLED FLOW BOILING FROM A SINGLE ELEMENT WAS FOUND TO AGREE WELL WITH THE MULTIPLE-FLUSH-ELEMENT DATA IF THE LOCAL FLUID SUBCOOLING AT THE LAST ELEMENT WAS USED IN THE CORRELATION. AT LOWER VELOCITIES THE DATA DEVIATED FROM THE PREDICTED VALUES.
