IHS ESDU Convective heat transfer during crossflow of fluids over plain tube banks. 73031

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.
