Abstract

Abstract

Tests were performed in narrow rectangular gap channels to research the effect of asymmetri-cal heat flux on critical heat flux（CHF） using Freon-12 as the coolant.By testing four heated ratios in the research,we studied the effect of mass flux,inlet temperature and outlet quality on CHF.In addition,we studied the asymmetrical heat effect and found that the critical heat flux increases as the asymmetric heated ratio increases at low outlet quality,the effect is weakened when outlet quality increases,and it is the oppo-site that CHF changes with heated ratios at high outlet quality.
