Models for the flow of a Bingham fluid within a porous material will be derived. These include unidirectional flows of various kinds, flows in structured 2D domains such as square, triangular and hexagonal networks, and flows in random 2D networks. Some these ideas will then be applied to convective flows of Bingham fluids. Nonlinear computations are also presented, and it is found that the flow patterns are strongly affected by the detailed microstructure. We consider briefly some free convective flows in sidewall-heated cavities and the porous medium analogue of the Bénard problem. In the latter case the basic state is linearly stable for all values of the Rayleigh number, but large-amplitude disturbances can cause convective motion.
