Abstract

A steam generator functions as a heat exchanger within nuclear power facilities, transferring heat from the primary coolant to the secondary coolant, which then produces steam using thermal energy from the reactor core. When designing steam generators, it is crucial to assess the vibrations of tube bundles caused by the gas-liquid two-phase flow occurring outside the heat transfer tubes. Numerous 3-D thermal-hydraulic codes have been developed and validated over the years. This paper offers a thorough review of recent 3-D thermal-hydraulic codes for steam generators, focusing on publications from 2014 to 2023. It summarizes the constitutive equations related to heat transfer and flow resistance included in these recent codes, providing an overview of the latest understanding of gas-liquid two-phase flow. Furthermore, the paper analyzes and presents experimental data used for code validation, along with the validation results of these recent codes.

基于多孔介质方法的蒸汽发生器热水力模拟程序的开发与验证

蒸汽发生器在核电设施中起到热交换器的作用，将热量从一次冷却剂传递到二次冷却剂，然后二次冷却剂利用反应堆堆芯的热能产生蒸汽。在设计蒸汽发生器时，对热管外气液两相流引起的管束振动进行评估是至关重要的。多年来，已经开发并验证了许多三维热水力规范。本文对最近的蒸汽发生器三维热工规范进行了全面的回顾，重点是2014年至2023年的出版物。总结了这些最新规范中有关传热和流动阻力的本构方程，概述了对气液两相流的最新理解。此外，本文还分析并给出了用于代码验证的实验数据，以及这些最新代码的验证结果。

期刊介绍： Progress in Nuclear Energy is an international review journal covering all aspects of nuclear science and engineering. In keeping with the maturity of nuclear power, articles on safety, siting and environmental problems are encouraged, as are those associated with economics and fuel management. However, basic physics and engineering will remain an important aspect of the editorial policy. Articles published are either of a review nature or present new material in more depth. They are aimed at researchers and technically-oriented managers working in the nuclear energy field. Please note the following: 1) PNE seeks high quality research papers which are medium to long in length. Short research papers should be submitted to the journal Annals in Nuclear Energy. 2) PNE reserves the right to reject papers which are based solely on routine application of computer codes used to produce reactor designs or explain existing reactor phenomena. Such papers, although worthy, are best left as laboratory reports whereas Progress in Nuclear Energy seeks papers of originality, which are archival in nature, in the fields of mathematical and experimental nuclear technology, including fission, fusion (blanket physics, radiation damage), safety, materials aspects, economics, etc. 3) Review papers, which may occasionally be invited, are particularly sought by the journal in these fields.
