Abstract

A computational fluids dynamics code called SPEED has been developed to simulate the 3D in-cylinder flow field and turbulence in arbitrarily shaped combustion chambers. It will operate successfully with non-orthogonal, unstructured and locally refined meshes, allowing accurate definition of any chamber geometry. The code is compatible with any mainframe computer system using FORTRAN 77, and runs with good numerical efficiency in terms of CPU times. Its main restriction is the limited availability of automatic mesh movement routines to aid successful manipulation of complex meshes through a full simulation cycle. A well developed pre and post processing environment is available, using two major commercial CAD packages, PATRAN and SUPERTAB. KIVA and GEM mesh generating packages are also included in the preprocessing environment. The user friendly environments enable mesh generation with detailed checking of the mesh to be completed before the run, and full visualisation of the data fields in 2D and 3D from the output data. The code has undergone extensive testing on a wide range of geometries during its development. LOA measurements from a dedicated experimental programme and from the JRC have been used to validate the code, and have given encouraging results. Further validations are still in progress.
