中文摘要: |
针对一种阵列式微管道换热器,利用FLUENT软件对其进行了数值模拟。将恒壁温、恒热流和流固耦合计算方

结果与实际情况吻合较好,能够为微管道换热器结构优化设计提供参考依据。 |
英文摘要: |
The numerical simulation on the fluid flow and coupled heat transfer of arrayed microchannel heat exchanger
was performed by using FLUENT software. Three numerical simulation models such as constant wall temperature,
constant heat flux and fluid solid coupling were taken into account. The results show that the coupled heat transfer model
of both the shell and sheet fluid flow can exhibit the local temperature change of heat exchanger truly. The simulation
results are agreement with the actual situation and can provide a reference for the optimization design to microchannel
heat exchanger. |
