摘要

以太阳盐为工质,实验研究熔盐横向冲刷管内汽-液两相流的传热特性。分析熔盐质量流速、熔盐入口温度、水侧压力、水侧质量流速、水侧干度对熔盐与汽-液两相流的传热特性的影响规律。实验结果发现熔盐入口温度及水侧干度对熔盐蒸汽发生器的性能影响较大。

Abstract

A binary mixture solar salt was used as a working fluid to experimentally study the heat transfer characteristics of molten salt and vapor-liquid two-phase flow in a shell-tube heat exchanger. The impact of solar salt mass flow rate, solar salt inlet temperature, water pressure, water mass flow rate and water dryness on the heat transfer characteristics of the heat exchanger is analyzed. Among them, the molten salt inlet temperature and water dryness have a great impact on the heat transfer characteristics.
