Conventional Engineering Application and Validation
Conventional Engineering Application and Validation
All conventional CFD simulations are carried out in AVICARI self-developed aeronautical numerical simulation platform ARI_CFD. Using commercial software standards and specifications as design basis, ARI_CFD can accept grids from self-developed software and commercial softwares like ICEM, Gridgen and Pontwise, support self-adapted grid, dynamic overset grid and deformed grid, and can be used to simulate steady and unsteady flow field with governing equation of EULER or N-S plus turbulent model. Inviscid flux difference scheme includes center difference scheme and upwind difference scheme (flux vector splitting and flux difference splitting schemes), while viscous flux spatial discretion scheme using center-type scheme. In ARI_CFD platform, there are more than 20 turbulence models (including transition model) and many boundary types to choose, simulation efficiency is improved by using multi-grid to accelerate convergence.
