在3MPa压力下对垂直下降管内绝热汽水两相流截面含汽率进行了理论及试验研究。结果表明,在低含汽率区,截面含汽率大于容积含汽率;在高含汽率区,截面含汽率小于容积含汽率。本文建立的模型能与试验数据较好吻合。
Under the pressure of 3MPa, the theoretical and experimental research on the steam content of the two-phase flow cross-section of adiabatic soft water in vertical descending pipe was carried out. The results show that the gas content in the section with low gas content is larger than the gas content in the section with low gas content and the gas content in the section with high gas content is less than the gas content in the area with high gas content. The model established in this paper can be in good agreement with the experimental data.
