Abstract
This paper establishes exponential decay bounds for solutions of the Forchheimer equations in semi-infinite pipe flow through a porous medium when homogeneous initial and lateral surface boundary conditions are applied. We investigate the decay for zero net flow and for nonzero net flow separately. (C) 2002 Elsevier Science Ltd. All rights reserved.
