In a word, the flow field and temperature field can be simulated in detail by numerical calculation of turbulent current model rather than porous medium model. And longitudinal-flow heat exchange has preferably performance by analysis.
本文的研究表明：在用数值方法模拟换热器中的流场与温度场时，采用湍流模型可以比用多孔介质模型获得更详细、准确的换热器内部流场与温度场信息；同时，本研究对换热器进行的性能分析也表明纵流式换热器有较好的流动与传热特性。
