摘 要：Experimental results are reported for the flow boiling heat transfer characteristics of nonazeotropic refrigerant mixture of R32 and R134a(25%/75%) in a microchannel with d=0.86 *** research results show that when the mass quality is greater than 0.1,the mass quality and mass flux have almost no effects on the heat transfer coefficients of flow *** transfer coefficients of the flow boiling in the microchannel are dependent mainly on heat *** is dominant in the heat transfer process for most *** flow boiling heat transfer coefficients in microchannel are 30%—200% higher than those in normal *** correlation is presented with deviation of no more than 25%.
