Multi-Block Structured Grid Generation Method for Computational Fluid Dynamics
Journal Title: Scholars Journal of Engineering and Technology - Year 2017, Vol 5, Issue 8
Abstract
Multi-block structured finite element grid generation algorithm is developed in conjunction with a homotopy technique. The computational domain is divided into a number of quadrilateral regions that takes into consideration topology and coordinates details of each sub-domain. The inner and outer boundaries of the computational domain are described in terms of the surface coordinates. Each sub-domain is designated with an eight nodes isoparametric finite element to generate orderly structured grid and homotopy method is employed to generate grid clustering for numerical flow field simulation. The grid clustering can be controlled by selecting proper stretching factor in order to flow field features such as to resolve boundary layer, to capture shock wave and to locate high pressure gradient region. The grid generation is in two-dimensional plane that can be rotated to obtain a three-dimensional grid arrangement over axisymmetric configuration. Major features of the present grid generation technique are convenient for checking the grid independence test of flow simulation with varying stretching factor. Major attraction of the present algorithm maintains geometrical conservation of computational domain method. The grid plots can be visualized with the aid of MATLAB. The grids can easily link with user developed flow solver or it can also be coupled with commercial flow solver. Keywords: finite element method, grid generation, computational fluid dynamics.
