The corresponding uneven gas pressure distribution creates a body force that is taken into account through Darcy's law. By using spatial averaging, the formulation, even though essentially one-dimensional in space, includes effects due the geometry of the container. An efficient and robust numerical scheme based on a differential algebraic equation formulation is proposed and implemented. Various computational results are presented and discussed to establish the validity of the approach.}, number={8}, journal={INTERNATIONAL JOURNAL OF NON-LINEAR MECHANICS}, author={Coffey, KA and Gremaud, PA}, year={2003}, month={Oct}, pages={1185–1194} }
