circular conduit meaning in Chinese

园形管道

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。
