Study And Realization Post-processing Software For Numerical Simulation Of Gas-particle Two-phase Flow

With the development of computer technology, Computational Fluid Dynamics (CFD) was used in automobile field and chemical field in early 1980th. In last ten years, the calculation and storage ability of computer have been increased greatly, but the computer price was reduced rapidly. At the same time, the cost of experiment increase continuously. The accuracy, reliability and calculation efficiency of CFD software increase rapidly because of continuously studying CFD. The ability of the CFD was being from qualitative analysis to quantify analysis, and the CFD can replace parts of or all of experimentation. The CFD was widely used in the field of engineering design. The post-processing of current CFD program just can process the data which was output itself. And the calculation speed of current CFD was needed to increase, so it is require a program which can process graphics professionally, fast, efficiently and exactly.Based on Visual C++ and MFC, the post-processing program interface of CFD was designed in the thesis. The thesis was researched the result data to read it in the right way. In the thesis, based on VC and OpenGL, studied the post-processing program which processes the pressure field, velocity field and volume percentage of numerical simulation. With the system tool of VC, this program was appended human assistant tool to use it conveniently.This thesis was focused on the scheme of equivalence belt filling and the arithmetic of creating equal numerical value line, and presented an improved method for drawing isograms. It can reduce the difficulty of coding and the quantity of calculation. This thesis was discussed the mathematics resolution of vector arrowhead, and chooses comparatively rational analytical mathematics method to reduce the quantity of calculation. A good result can be got by use of this software. So it is effective.
