Abstract
This work considers the time-dependent anisotropic penetrative convective Darcy flow in a semi-infinite cylinder. An exponential decay estimate in terms of the distance from the finite end of the cylinder is obtained from a differential inequality for an energy integral. The work also indicates how to bound the total energy. (c) 2005 Elsevier Ltd. All rights reserved.
