NUMERICAL ANALYSIS METHOD USING 2-DIMENSIONAL FINITE VOLUME MODEL APPLICABLE TO MIXED MESHES |
摘要 |
PURPOSE: A fluid flow analysis method of a 2D finite volume method, capable of applying a mixed mesh is provided to find an adjacent mesh of a computational mesh and to compute a flow ratio at a mesh boundary side. CONSTITUTION: Fluid flow is analyzed by using a conservation variable of computational meshes. The conservation variable is obtained by a flow ratio and a generating function in boundary sides of a computational mesh and an adjacent mesh. The computational mesh and the adjacent mesh are distinguished through a property which shares two breakpoints(S150). The computational mesh is formed with a triangular mesh at a point which change of a flow velocity property and a flow property is large. The rest is formed with a rectangular mesh. [Reference numerals] (S110) Step of finding an angle between a central coordinate of a computational mesh and nodal points; (S120) Step of determining a sequence of the nodal point; (S130) Step of reading a nodal point number; (S140) Step of repeating the same steps for residual meshes; (S150) Determining a mesh with two same nodal points as an adjacent mesh
