要約

Laminar flow in a curved channel with a rectangular cross section is investigated. The channel is occupied by a fluid-saturated porous medium. The flow is driven by a constant azimuthal pressure gradient. The Brinkman extension of the Darcy law is utilized; the momentum equation takes into account the Darcy and Brinkman drag terms. An analytical solution for the velocity field is obtained using a generalized Fourier series. The velocity profile depends on the geometry of the channel (the inner and outer radii of the channel walls and the aspect ratio of the cross section) and the Darcy number.
