Turbine CFD Grid Generation

The paper studies the various methods for structured and unstructured mesh generation technology , developed a variety of mesh generation software program , and example to verify the robustness of these procedures . On this basis , the application of these to the grid generation technique in around the blades of the impeller generates a structured and unstructured grids . Structured mesh generation method including algebra and differential equations . The papers detailed study technical details of the software development of these methods , and analysis of the program implementation process, a program module that implements these methods . At the same time , the analysis of these two methods to deal with the scope of the problem and procedures to achieve the degree of difficulty , and evaluation of the quality of the mesh generation , and to provide a basis for turbomachinery grid generation method to generate high-quality selection . Unstructured mesh generation methods including Delaunay triangulation methods and advancing front method . The technical details of the paper a detailed study of Delaunay triangulation method of software process and software development , the introduction of a certain geometric parameters of the technological improvements , the standard of quality parameters of the evaluation grid and grid optimization method provides accelerate the technical means to generate high-quality meshes , the architecture of the methods and procedures to achieve reasonable and efficient data structures . On this basis , the method in turbomachinery grid generated program modules .
