采用圆形通道实验本体对饱和沸腾传热特性进行实验研究。实验本体加热长度1000 mm,通道尺寸为φ9.5 mm×1 mm。采用全液相雷诺数(Relo)和沸腾数(Bo)作为描述圆形通道内饱和沸腾传热特性的无量纲参数,在实验数据的基础上,拟合获得了圆形通道内饱和沸腾传热系数经验关系式,关系式对94.5%实验数据预测偏差在±20%以内。 Experimental study on the heat transfer characteristics of saturated boiling is carried out by using circular channel experiment body. Experimental body heating length of 1000 mm, the channel size is φ9.5 mm × 1 mm. The Reynolds number and boiling number (Bo) were used as the dimensionless parameters to describe the heat transfer characteristics of saturated boiling in a circular channel. Based on the experimental data, the saturated boiling heat transfer Coefficient empirical relationship, the relationship between 94.5% of the experimental data prediction deviation within ± 20%.
