目前对气水两相流的分相流量的研究中,多是针对两相流总流量和液相分相流量进行,对气相分相流量的研究很少。本文利用文丘里管和含气率传感器对空气水两相流气相流量计算方法进行了研究,在均相流模型基础上考虑了滑速比因素造成的影响,探讨了两相流气相流量计算方法。结果表明,该方法相对于传统的均相流模型在计算精度上得到了显著提高。
It is very important to investigate of gas phase flow rate of gas-water two-phase flow. However, most researches just focused on liquid phase and total flow rate of two-phase flow. Gas phase flow rate of two-phase flow was studied based on homogeneous flow model with slip model used void fraction sensor and venturi tube in this paper. Experimental results show the homogeneous flow model with slip model plays an important role in calculating gas phase flow rate and the model has a more high accuracy than traditional homogeneous flow model.
