| Abstract: | Experiments of heat transfer coefficient and flow resistance of air flowing obliquely across round tube bundles have been investigated in this paper. The experimental data have been correlated and the correlation results are presented, which can provide the design data for air flowing obliquely across tube bundles. The experiments indicate that better integrated performance of heat transfer enhancement can be obtained by air flowing obliquely across round tube bundles than by vertically across them. |
