Turbulence Modeling.
Abstract
Beginning with the code flo103 of Jameson and Martinelli, a robust, flexible numerical platform has been constructed which can accept O and R meshes as well as C, accepts a variable number of PDEs in the turbulence models, has consistent gradient compensation enhanced multi-grid sequencing, a restart option, various post-processing options, the option of recording convergence histories, accepts k-e, k-e-S, second order and Baldwin-Lomax turbulence models, has dynamical memory allocation, vectorized data structure and Unix integration, and computes subsonic, transonic and supersonic flows. Virtually any turbulence model can be run in essentially any two-dimensional geometry, so that they can be compared on an equal footing. The following cases have been computed: homogeneous grid turbulence; plane jet and mixing layer; flat plate boundary layers; semi-infinite plate (subsonic (Clauser) and supersonic (Delery)); finite plate (subsonic (ONERA)); supersonic compression ramp (Settles et al - Mach 2.93); Delery bump. Documentation is in preparation.
