摘　　要：以垂直向上窄缝矩形通道内去离子水为流动介质,对单相等温流动及恒热流密度条件下的单相传热进行了实验研究。结果表明,窄缝矩形通道内的单相等温流动特性及单相传热特性并未偏离常规尺度通道内的相关规律,采用经典理论解或关系式能获得较好的预测结果。With deioned water as the test fluid,the experiments involved the single-phase isothermal flow and convective heat transfer with the boundary condition of constant heat flux were conducted in an upright narrow rectangular duct.The results show that the single-phase flow and heat transfer in the test duct did not deviate compared to the case in large-sized pipes,and can be well predicted by the conventional theoretical values and experimental correlations.
