Numerical Methods, Simulations and Visualization for Compressible Flows (original) (raw)

Summary

In this paper we want to describe how we solved an industrial flow problem, the simulation in a simplified two—stroke engine. The numerical method we are using is an upwind finite volume method on an unstructured grid with arbitrary finite volumes. The grid fineness is adapted locally to a get a better resolution of important flow structures. The boundaries of the calculation domain are moving. Essential for the development for such a numerical algorithm is the graphical support to find programming errors and of course to visualize the calculated data. We will analyse the demands for the necessary graphics, which is provided by the graphical programming environment GRAPE. Furthermore we will present some of the numerical results of standard test problems in 2D and 3D to validate our numerical algorithm.
