| 摘 要： | 以去离子水为工质,在1.0～6.0MPa压力范围内,对大宽高比(1.0×60mm、1.8×60mm、2.5×60mm)矩形狭窄通道内两相沸腾的换热特性进行了实验研究.分析了压力、窄缝间隙、热流密度、质量流量、含汽率等参数对矩形窄缝通道内水的沸腾换热的影响,得到了矩形窄缝通道内沸腾换热经验关系式,与实验数据符合良好.

| Abstract: | The characteristics of boiling heat transfer were experimentally investigated in narrow rec-perimental data well.tangular channels with large width-height ratio at pressure ranging from 1.0 to 6.0MPa.The effect of pressure,heat flux,mass flux,gap size and quality on the heat transfer was analyzed.At last,a new developed correla-tion calculated heat transfer coefficients was obtained in narrow rectangular channels,which can predict ex- |
