摘要
本文提出了运用多孔介质模型、分布阻力模型和k-ε湍流模型对壳侧为翅片管束的壳管式换热器壳侧速度场与温度场进行三维数值模拟的方法,并对一相应类型换热器壳侧的流动与换热进行了数值模拟,得出了壳侧流场参数的图示以及壳侧进出口压降,温差,换热量随壳侧Re变化的特性曲线。
In this paper a three-dimensional numerical simulation model is proposed which uses porous media, distributed resistance concepts and k-epsilon turbulence model to simulate shell-side velocity and temperature fields of shell-and-tube heat exchangers with finned rod bundles. The fluid flow and heat transfer characteristics of shell-side fluid are revealed, and the variations of pressure drop, temperature difference between inlet and exit of the shell side fluid with Reynolds number are obtained.
