In this paper, a full-scale three-dimensional shell-and-tube heat exchanger (STHEX) was analyzed in the steady state with the standard k-ε and realizable k-ε turbulence model, respectively. The pressure drop predicted by the standard k-ε and the realizable k-ε turbulence model has a large deviation from each other, but the outlet temperature prediction shows a very small difference. The hot water temperature at the shell outlet was 9.4°C cooler than the given target value of 40°C, and the temperature of the cooling water at the tube outlet was 4.43°C higher than the target value of 27.6°C indicating that the overall heat transfer area of STHEX was designed excessively. On the other hand, predicting the excessive heat transfer area through numerical analysis of the large STHEX of the full size is judged to have saved a significant amount of time and money in the trial and error design and performance check of the heat exchanger.
