Resumen en inglés

A new algorithm has been developed to compute low Mach Numbers supercritical fluid flows. The algorithm is applied using a finite volume method based on the SIMPLER algorithm. Its main advantages are to decrease significantly the CPU time, and the possibility for supercritical fluid flow modelisation to use other discretisation methods (such as spectral methods and/or finite differences) and other algorithms such as PISO or projection. It makes it possible to solve 3D problems within reasonable CPU time even when considering complex equations of state. The algorithm is given after first a brief description of the previously existing algorithm to solve for supercritical fluids. The side and bottom heated near critical carbon dioxide filled cavity problems are respectively solved and compared to the previously obtained results.< Leer menos
