Critical heat flux phenomena in spray cooling
Abstract
This paper addresses critical heat flux phenomena in high-heat-flux spray cooling. Experimental investigations and analysis were performed to determine the mechanisms causing transition to critical heat flux. Measurements were taken with a laser phase Doppler particle analyzer which indicate that the CHF is caused in some cases by a deficiency in liquid supply due to droplet entrainment, splashing, and expulsion from nucleating bubbles.
