CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishIn this work, fully explicit numerical solutions for heat and fluid flow in cylindrical domains, completely or partially filled with a fluid saturated porous medium, are presented. Laminar natural convection in a vertical porous annulus and in a vertical annulus with a centrally located heat generating rod, and laminar forced convection in a pipe partially filled with a porous medium are numerically simulated. Novel stability conditions are carried out for the fully explicit Artificial Compressibility (AC) version of the Characteristic Based Split (CBS) algorithm, in order to effectively solve the above problems. The results presented in this paper are validated against experimental and numerical results available from the literature.

Novel stability conditions are carried out for the fully explicit Artificial Compressibility (AC) version of the Characteristic Based Split (CBS) algorithm, in order to effectively solve the above problems.
