两相闭式热虹吸管换热特性的数值模拟

Modeling and Simulation of Heat Transfer Characteristics in Two-Phase Closed Thermosyphon

本文建立数学模型对两相闭式热虹吸管换热特性进行数值模拟。考察了几何尺寸、工质及加热条件对液膜流态、液膜厚度等的影响。

One-dimentional.steady-state numerical model was devoloped to simulate the operation of closed,two-phase thermosyphon based on the previous experimental and theoretical studies.This model is used to analyse how the parameters of geometry,fill chorge,working fluid and heating or coding conditrons affect the heat transfer characteristics.Such analysis is helpful to understand the internal mechanism of the operatton in the closed,two-phase thermosyphon.This work can be used for optimisation study and design of thermosyphon.
