Sommario/riassunto |
|
Authored by a respected scientist with a growing international reputation this is a self-contained text that can be used by the beginners and the experts alike, to study the basic aspects of finite element modelling. It provides a sound physical understanding of the basis on which mathematical models of polymer processes are built.* Written from a chemical engineering rather then a mathematical perspective it enables the reader to get up to speed in a relatively short time* Provides the 'parts and tools' required to assemble finite element models, applicable to situations that arise under realistic conditions* Discusses and compares specific finite element schemes that provide the most reliable and robust numerical solution procedures for polymer processing models* Practical examples give a wide ranging view of the application of finite element analysis to industrial problems* Describes non-Newtonian fluid mechanics equations in a self-contained, concise and clear manner* Includes clear and simple readily compiled code to model simple problems that can be extended to solve more complex polymer processing problemsThis book makes the subject accessible to a wide audience ranging from senior under-graduate to post-graduate engineering students, as well as, researchers and practising engineers involved in polymer industry. |
