Abstract: Gas flows inside and around rapidly rotating bodies made of cellular-porous materials are studied numerically and experimentally. Within the framework of the previously proposed physicomathematical model, an appropriate numerical algorithm is developed and tested. Internal flows and a conjugate problem with the external flow are considered. The calculated moment and dynamic pressure are in good agreement with experimentally measured characteristics of a rotating porous disk on a solid substrate.

Keywords: cellular-porous materials, rotation, internal and external flows, experiment, numerical simulation.
