ESDU 73031 gives a method for estimating the heat transfer from a bank of plain tubes in fluid crossflow (as@ for example@ in a shell-and-tube heat exchanger). The data apply to single-phase gas or liquid flow and were obtained by an empirical correlation of experimental results from a wide range of sources. Graphs enable mean heat transfer from the complete bank to be estimated when the tubes are in-line or staggered@ and allow for variation of fluid properties with temperature and@ if appropriate@ tube inclination to the flow. The heat transfer from individual rows of the bank can also be predicted. From a comparison of the method with experimental results it is accurate to within 15 per cent.
