Heat transfer characteristics of a collapsing two-phase bubble in an immiscible liquid: experimental correlation

摘要

Experimental studies on collapse of n-pentane, isopentane and furan bubble in immiscible liquids like water and aqueous glycerol (75 wt% and 98.3% wt) are reported. Heat transfer characteristics indicate little variation in condensation heat transfer coefficient up to a condensation ratio, xk, of 0.8. For xk<0.8, sharp decline in the heat transfer coefficient is observed. Instantaneous complete condensation was observed at high value of /spl Delta/T (/spl ges/15/spl deg/C), and no condensation was observed at /spl Delta/T/spl les/2.5/spl deg/C.
