基于Matlab PDETOOL的滲流力學(xué)可視化教學(xué)與上機(jī)實(shí)驗(yàn)
[Abstract]:In order to improve the classroom efficiency of seepage mechanics, aiming at the characteristics of seepage mechanics discipline and the common problems in teaching practice, The teaching method of introducing Matlab PDE toolbox into classroom is put forward. The method and steps of solving the classical mathematical model in seepage mechanics by PDE toolbox (PDETOOL) in Matlab are introduced, and the common mathematical models and boundary conditions of oil and gas seepage are summarized. The classical models of seepage mechanics, such as one source, one sink, two sources and two sinks, steady seepage and elastic unstable seepage are numerically simulated by PDETOOL. The visualization of pressure field and flow field of each classical seepage model is realized. It is helpful to help students understand abstract concepts such as stream function, pressure wave and pressure conductivity, deepen students' perceptual understanding of abstract processes such as pressure wave propagation, unstable seepage and pressure exhaustion, and promote students' interest and enthusiasm in class. At the same time, it puts forward the teaching suggestion of adding computer experiment content in the course of seepage mechanics teaching, giving full play to the advantages of visual teaching, and laying the foundation for the courses of numerical simulation and reservoir engineering, etc. Make students to the whole knowledge system of petroleum engineering produce macroscopic understanding, improve teaching quality.
