摘要
Abstract
By simplified the model of shell-and-tube heat exchangers, adopted the unstructured mesh, chose the k-S turbulence model to gain the static temperature field, velocity field and static pressure field distribution of shell by taking numerical simulation of the shell side turbulent flow and heat transfer process with the CFD software FLUENT at different baffle spacing. Analyzed the effect of baffle spacing on the distribution of shell fluid flow, heat transfer rate and pressure drop, also acquired the relationship between inlet velocity and heat transfer rate, pressure drop. The simulation results consistent with the theoretical results of shell-and-tube heat exchangers, which can be a reference for the design and improvement of shell-and-tube heat exchangers.关键词
