Dealing with general problems in fluid mechanics, convection diffusion, compressible and incompressible laminar and turbulent flow, shallow water flows and waves, this is the leading text and reference for engineers working with fluid dynamics in fields including aerospace engineering, vehicle design, thermal engineering and many other engineering applications. The new edition is a complete fluids text and reference in its own right. Along with its companion volumes it forms part of the indispensable Finite Element Method series.

New material in this edition includes sub-grid scale modelling, artificial compressibility, full new chapters on turbulent flows, free surface flows and porous medium flows, expanded shallow water flows plus long, medium and short waves, and advances in parallel computing.

* A complete, stand-alone reference on fluid mechanics applications of the FEM for mechanical, aeronautical, automotive, marine, chemical and civil engineers.
* Extensive new coverage of turbulent flow and free surface treatments
* Accompanied by downloadable FEM source code
