Description
WIT Press Advances in Fluid Mechanics 2010 Edition by M. Rahman, C. A. Brebbia
This book reflects the state of the art in fluid mechanics. The study of fluid mechanics involves various properties of the fluid, such as velocity, pressure, density and temperature, as functions of space and time. Featuring the latest developments, this book contains edited versions of the papers presented at the Seventh International Conference on Advances in Fluid Mechanics. Contributors from all round the world cover a wide range of topics, while particular emphasis is placed on new applications and research currently in progress.Invaluable to scientists, engineers and other professionals interested in the latest developments in theoretical and computational fluid mechanics, this volume encompasses: convection, heat and mass transfer; experimental versus simulation methods; computational methods in fluid mechanics; multiphase flow; boundary layer flow; non-newtonian fluids; hydraulics and hydrodynamics; wave studies; industrial applications; biofluids; turbulence flow; permeability problems; environmental fluid mechanics; petroleum engineering applications; and fluid structure interaction.
