Surprisingly, initial numerical tests indicated that the 1/2-equation model produces comparable velocity statistics at reduced cost. It is also a test problem and first step for developing numerical analysis to address a full 1-equation model. This report begins the numerical analysis of the 1/2 equation model. Stability, convergence and error estimates are proven for a semi-discrete and fully discrete approximation. Finally, numerical tests are conducted to validate our convergence theory.", "revisions": [ { "version": "v1", "updated": "2024-05-29T22:44:00.000Z" } ], "analyses": { "keywords": [ "numerical analysis", "turbulence", "model produces comparable velocity statistics", "test problem", "urans model" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
