Produktbeschreibung

This product, consisting of a CD-ROM and a book, deals with the numerical simulation of reactive transport in porous media using the simulation package SHEMAT/Processing SHEMAT. SHEMAT (Simulator for HEat and MAss Transport) is an easy-to-use, general-purpose reactive transport simulation code for a wide variety of thermal and hydrogeological problems in two or three dimensions. The book is a richly documented manual for users of this software which discusses in detail the coded physical and chemical equations. Thus, it provides the in-depth background required by those who want to apply the code for solving advanced technical and scientific problems. The enclosed companion CD-ROM contains the software and data for all of the case studies. The software includes user-friendly pre- and post-processors which make it very easy to set up a model, run it and view the results, all from one platform. Therefore, the software is also very suitable for academic or technical "hands-on" courses for simulating flow, transport of heat and mass, and chemical reactions in porous media. You can find a link to the updated software on springer.com .

Rezensionen

From the reviews:

"The primary audience for this text consists of hydrogeologists and geophysicists. ... It aims to provide a systematic introduction to the software SHEMAT ... . Overall, the material is well presented. The philosophy of the book, to present the necessary mathematical background ... is well thought through. It should be able to fill a dual role of being a user guide and an introduction into the modelling and simulation of flow in hot aquifers." (Ute Mueller, The Australian Geologist, Issue 128, 2003)
