摘 要:In the paper,condensation heat transfer of onazeotropic mixtures R1l/R1l3in in-line and staggered 3-row smooth tubes and petal shaped fin tubes was studied under natural convec tive *** results showed that,either in-line or staggered,the effect of bun dle for nonazeotropic ixtures in petal-shaped fin tubes was very smaller,at the same condition,it averge condensation heat transfer coefficient is l.5-5 times larger than of smooth tubes.
