蒸汽直接接触冷凝换热特性实验分析
Experimental analysis on heat transfer characteristics of steam direct contact condensation
摘要
Abstract
[Objective]To support the design and optimization of containment suppression devices for small modular reactors,this study investigates the heat transfer characteristics of steam direct contact condensation.[Methods]A thermal and visual experimental study is conducted on the phenomenon of steam direct con-tact condensation using a pressure suppression simulation experimental apparatus.An analysis is then made of the effects of the non-condensable gas fraction,steam mass flow rate and cooling water subcooling degree on the condensation heat transfer properties.[Results]The experimental findings demonstrate that increasing the mass fraction of non-condensable gases weakens steam condensation heat transfer.Both the steam mass flow rate and cooling water subcooling degree have multifaceted impacts on the steam condensation heat trans-fer process.[Conclusions]The deviation between the predicted values from the proposed steam direct con-tact condensation heat transfer model and the experimental measurements is within±20%,indicating that the model accurately represents the physical process of steam direct contact condensation heat transfer.关键词
