Examples
- In the numerical solution algorithm , the method of characteristics , analytic method and galerkin finite element method ( galerkin - fem ) can be chosen to solve the advective equation , diffusion equations , reaction ( source / sink ) equations , propagation equations and pressure poisson equation , respectively . the developed new algorithm has been verified using analytical solution of circular conduit flow in a reynolds number range of 100 < re < 1 000 and experimental data of the laminar flow over a backward - step facing step . the flow properties are well characterized by this three - dimensional numerical model
本论文在评述三维粘性流动数学模型已有研究成果的基础上，着重在数值计算方法的选择和定解条件的给定对数学模型计算结果的影响进行了研究，并首次提出了求解三维纯对流方程的高精度的拟协调单元法，建立了三维低雷诺数re流动的数学模型，并在圆管流动、台阶突扩矩形管道流动中得到验证和应用。 - The research on vertical conduit flow of gas - liquid two phases in wellbore aims at the classification , transition and judgement of flow pattern , according to the pressure distribution of oil - gas - water mixture in wellborne , by which the reliable basis will be provided for understanding of well performance , rational control / monitoring and regulating of well flow regime and the design of gas lift
摘要井筒两相管流研究的主要目的是用于井筒内流体流型的划分和流型的转变与判断，其基本依据在于井筒内油气水混合压力的分布状况；在了解了井筒混合流体的压力分布状况之后，能够为掌握油井生产规律、合理控制和调节油井式作方式及气举设计提供可靠的依据。
