The use of Computational Fluid Dynamics to simulate and predict fluid flows, heat transfer and associated phenomena continues to grow throughout many engineering disciplines. On the back of ever more powerful computers and graphical user interfaces CFD provides engineers with a reliable tool to assist in the design of industrial equipment often reducing or eliminating the need for performing trial-and-error experimentation.

An Introduction to Computational Fluid Dynamics is the ideal text for the newcomer to the area whether they be undergraduates, graduates, or professionals. It provides thorough yet accessible coverage of commercial finite volume based CFD codes within the context of the underlying theory, giving the reader a full appreciation of CFD and its numerous engineering applications.

Key features

• Offers essential support for novice users of commercial CFD codes such as ANSYS CFX, FLUENT, STAR-CD and PHOENICS.
• Covers fluids and turbulence physics together with computational modelling techniques
• Uses a step-by-step approach to introduce the methodology
• Chapter summaries and worked examples throughout to reinforce understanding of the key concepts

New to this edition

• A new chapter describing unstructured meshing techniques
