摘要

为探究高压环境下多孔结构表面的压力、结构与材料对沸腾换热的影响，以去离子水为工质，通过沸腾除气消除工质中不凝气的干扰，在3～10 MPa高压范围内开展多工况对比实验，测试304不锈钢、20碳钢材料的光滑表面与多孔结构表面的壁面过热度和换热系数，结合沸腾气泡行为与表面特性分析换热性能的变化规律。实验结果表明：

多孔结构表面在高压下呈现与光滑表面相反的换热特性，当热流密度较高（55 kW/m

）时，压力从3MPa升至10 MPa，多孔表面过热度增加0.7 K、换热系数下降27.3%，而光滑表面过热度降低0.7 K、换热系数提升28.6%；多孔结构较光滑表面显著强化换热，热流密度15～60 kW/m

时，过热度降低1.2～1.3 K，换热系数强化比可达1.15～2.20；与304不锈钢相比，20碳钢热导率更高可使过热度最大降低0.5 K、换热系数提升9.7%，但20碳钢在高温水环境中易发生锈蚀，导致换热性能恶化。研究可为高压沸腾换热性能强化提供实验数据基础。

Abstract

To investigate the pool boiling heat transfer characteristics of porous surfaces under high-pressure conditions

the effects of pressure

surface structure

and material on boiling heat transfer are systematically analyzed in this study.Specifically

experiments were conducted as follows by using deionized water as the working fluid：The working fluid was pre-boiled to remove gas and eliminate non-condensable gas interference；comparative experiments were conducted under multiple working conditions with the pressure ranging between 3—10 MPa pressure to measure the coefficients of wall superheat and heat transfer on smooth and porous surfaces of structures made of 304 stainless steel and 20 carbon steel；variations in the heat transfer performance were analyzed based on boiling bubble dynamics and surface characteristics.The results reveal the porous surface exhibited a heat transfer behavior opposite to the smooth surface under high pressure.At elevated heat flux（55 kW/m

）

a 0.7 K rise in superheat and a 27.3% decline in heat transfer coefficient were observed for the porous surface as the pressure increased from 3 MPa to 10 MPa

whereas a 0.7 K reduction in superheat and a 28.6% improvement in heat transfer coefficient were noted for the smooth surface.The porous surface had significantly enhanced thermal performance：Within the heat flux range of 15—60 kW/m

superheat decreased by 1.2—1.3 K

and the heat transfer coefficient enhancement ratio reached up to 1.15—2.20.Compared to 304 stainless steel

20 carbon steel demonstrated superior thermal conductivity

reducing superheat by up to 0.5 K and improving hea

t transfer coefficient by 9.7%.However

20 carbon steel suffered accelerated corrosion in the high-temperature aqueous environment

which led to performance degradation.This study is intended to provide experimental data that may serve as a basis for the enhancement of boiling heat transfer performance under high-pressure conditions.
