本文所述的计算机程序能够模拟这种形式的任何热虹吸回路的行为。该项目是ASHRAE根据RP-140“两相热虹吸回路性能标准的制定”赞助的一项大型研究的一部分。作为这项研究的结果而撰写的另外两篇论文，通过描述热虹吸回路运行特性的实验和计算机模拟研究结果，对本文进行了补充。本文概述了该程序执行的操作步骤，因为它以增量方式模拟循环周围流动的工作流体的状态。讨论了遇到的一些问题及其解决方案。还将模拟数据与实验数据进行了比较，以验证模拟结果的有效性。 引文:阿什雷学报，第83卷，第2部分，哈利法克斯，北卡罗来纳州

The computer program described in this paper is capable of simulating the behavior of any thermosiphon loop of the form. This program was developed as part of a larger study sponsored by ASHRAE under RP-140 "Development of Performance Criteria for Two-Phase Thermosiphon Loops.". Two additional papers, written as a result of this study, supplement this paper by describing the results of both experimental and computer simulation studies into the operating characteristics of thermosiphon loops.This paper outlines the operational steps carried out by the program as it simulates, incrementally, the state of the working fluid flowing around the loop. Some of the problems encountered are discussed along with their solutions. A comparison of the simulated and experimental data is also provided to check the validity of the simulated results.
