MATLAB PDE工具箱在稠油输送管道中的应用

摘要

Using Matlab PDE toolbox can depict the laminar flow field of the full development stages in heavy oil pipeline. Compared with theoretical calculation results, error of gained parameters is small. With refinement of the grid, the gained parameters are closer to the true value, which can provide a fast, accurate numerical solution for studying the flow of heavy oil in pipeline.%利用Matlab PDE 工具箱可以直接描绘出稠油输送管道中充分发展阶段的层流场,运行得到的参数与理论计算值相比误差很小,随着网格的精细化,更加接近于真实值,为管道内稠油的流动研究提供了一种直观、快速、准确、形象的数值求解方法.
