摘要建立了一个详细的二维计算流体力学模型，模拟了两相环流热虹吸管（TPLTS）内的两相流动和传热。建立了CFD模拟，以代表在各种操作条件下的瞬态和稳态操作分析的TPLTS的两相流动和传热现象。两相流采用VOF模型，蒸发和冷凝采用Lee模型。模拟结果与实验温度，压力和流动可视化数据进行了比较。
Abstract A detailed 2-D computational fluid dynamics (CFD) model simulating two-phase flow and heat transfer in a two-phase loop thermosyphon (TPLTS) is presented. The CFD simulation was built to represent two-phase flow and heat transfer phenomena during the transient and steady-state operation analysis of a TPLTS under various operating conditions. The two-phase flow was modeled using the volume of fluid (VOF) model, and the Lee model was utilized for evaporation and condensation. Simulation results were compared with experimental temperature, pressure, and flow visualization data.
