Abstract

An experimental study has been conducted on the free convection heat transfer for the 7 kinds of circular finned tube heat exchangers. Empirical correlation was suggested at the range of 3,500$D_o$/$D_i$<3.0, 0.19<$P_f$/$D_i$<0.34. The 92% of experimental data agreed with the correlation within 10%.
