Stability and Wave Motion in Porous Media

by Brian Straughan

Overview

This book presents an account of theories of flow in porous media which have proved tractable to analysis and computation. In particular, the t- ories of Darcy, Brinkman, and Forchheimer are presented and analysed in detail. In addition, we study the theory of voids in an elastic material due to J. Nunziato and S. Cowin. The range of validity of each theory is outlined and the mathematical properties are considered. The questions of structural stability, where the stability of the model itself is under cons- eration, and spatial stability are investigated. We believe this is the first such account of these topics in book form. Throughout, we include several new results not published elsewhere. Temporal stability studies of a variety of problems are included, indic- ing practical applications of each. Both linear instability analysis and global nonlinear stability thresholds are presented where possible. The mundane, important problem of stability of flow in a situation where a porous medium adjoins a clear—fluid is also investigated in some detail. In particular, the chapter dealing with this problem contains some new material only p- lished here. Since stability properties inevitably end up requiring to solve a multi-parameter eigenvalue problem by computational means, a separate chapter is devoted to this topic. Contemporary methods for solving such eigenvalue problems are presented in some detail.

Editorial Reviews

From the reviews:

"It offers an original approach to this multifaceted subject, not only because of the emphasis it puts on the stability issue, but also because of the exceptional variety of the problems addressed. … this is a highly recommendable book. People having already some knowledge of flows in porous media will be delighted to read it, and beginners will find a valuable guide to understanding many challenging problems, treated with mathematical rigour, but never forgetting the physics." (Antonio Fasano, Mathematical Reviews, Issue 2009 e)

“It could be used in a seminar where graduate students are asked to research and present detailed arguments for select problems which are only formulated by Straughan or maybe only briefly outlined. As a research text, it surveys a great many interesting problems and applications … with proper acknowledgment of and direction to the appropriate sources of the models and analysis. Thus, this text should be a valuable resource for anybody working on problems in the porous media field.” (Philip W. Schaefer, SIAM Review, Vol. 54 (2), 2012)
