Abstract:
The CFD method was applied to investigate the preformanee of heat transfer and fluid fow in spiral.ly inner finned tubes with different baflle spaeing, spiral angle, and fin height for 27 different groups combina.tion. The numerieal simulation results show that deereasing balle spacing can improve the performanee of healtransfer on shell side. However, the pressure drop of fluid flow inereases with deereasing of balle spacingBut the performanee of heat transfer inereases greater than the pressure drop dose with Reynolds number inereasing, and the enhaneed tube has better performanee compared with the smooth tube. With the fin heighiinerease, the comprehensive perormanee of enhaneed tube inerease more obviously at high Reynolds numberregion. The formulae of heat transfer and fluid flow are fitted and the comprehensive perormanee of the en.haneed tube is evaluated.
