Description 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.
Audience
Practicing engineers, senior students and researchers in mechanical, automotive, aeronautical and civil engineering. Key topic for applied mathematicians and engineering software developers.
