Abstract: | This paper concerns numerical simulation of flow through oil filters. Oil filters consist of filter housing (filter box),
and a porous filtering medium, which completely separates the inlet from the outlet. We discuss mathematical models, describing
coupled flows in the pure liquid subregions and in the porous filter media, as well as interface conditions between them.
Further, we reformulate the problem in fictitious regions method manner, and discuss peculiarities of the numerical algorithm
in solving the coupled system. Next, we show numerical results, validating the model and the algorithm. Finally, we present
results from simulation of 3-D oil flow through a real car filter. |
