新型分油机两相流场的有限元计算

Analysis and calculation of two-phase flow in the new purifier by the finite element method

采用两相流连续介质模型,对新型分油机内油水两相流动作了细致分析,并用有限元法解POISSON方程、N-S方程、连续方程的方法,对流场内压力场、速度场、浓度场进行了计算.计算结果与实际分油机分离现象相符,说明设计方案正确.为设计和维护保养提供一定依据.

After analyzing the two-phase flow in the new purifier by means of the continuum model, the POISSON equation, NAVIER-STOS equation and continuous equation are respectively derived and solved by using the finite element method. The solutions correspondingly on pressure, velocity and particle concentration fields coincide well with the phenomenon of separation between oil and water. This paper will also be in favour of design and maintenance of the purifier.
