| Abstract: | Based on reasonably simplifying the structure of large-scale finned tube heat exchanger,both computational fluid dynamics(CFD) and numerical heat transfer method were used to establish both internal flow and heat transfer's mathematical model of the finned tube heat exchanger and to obtain the distribution of internal flow and temperature field.Having the numerical simulation results compared with application data proves the feasibility of this method which provides the reference for the design and improvement on heat exchangers. |
| Keywords: | finned tube heat exchanger structure numerical simulation flow field |
