For turbulent flows at relatively low speeds there exists an excellent mathematical model in the incompressible Navier-Stokes equations. Why then is the 'problem of turbulence' so difficult? One reason is that these nonlinear partial differential equations appear to be insoluble, except through numerical simulations, which offer useful approximations but little direct understanding. Three recent developments offer new hope. First, the discovery by experimentalists of coherent structures in certa...

Proceedings of the 1995 Joint ASME/JSME Symposium on Numerical Developments in CFD. Topics include Newton-Krylov methods, adaptive techniques, segregated solvers, cell-vertex algorithms, pressure-based time-marching finite-volume algorithms, hybrid unstructured-grid methods, high-order infinite diff

A definitive guide for accurate state-of-the-art modelling of free surface flows Understanding the dynamics of free surface flows is the starting point of many environmental studies, impact studies, and waterworks design. Typical applications, once the flows are known, are water quality, dam impact and safety, pollutant control, and sediment transport. These studies used to be done in the past with scale models, but these are now being replaced by numerical simulation performed by software suite...

This volume contains 18 papers presented at the World Environmental and Water Resources Congress and Great Rivers History Symposium held in Kansas City, Missouri, from May 17 to 21, 2009. ""Great Rivers History"" focuses on the great rivers of the world and the engineering challenges of balancing the urgency for development and growth with the environmental need for a sustainable future. This seminal collection offers a fascinating history of: the Paris sewer system; the Turtle Creek Reservoir;...

This text is based on practical applications, worked examples, and information about underlying assumptions. It includes coverage of fundamentals, a range of applications and hypersonic flow and aerodynamic heating. An interactive PC program is available free to users over the Internet, and enables calculations of compressible flow properties related to the text.

A survey of the problems encountered in flood control and drainage engineering. Among the topics studied are: estimation of design flood; flood routing through reservoirs and channels; design of spillways; and flood mitigation through planning of reservoir capacities and operation of reservoirs.

"A new text/workbook that presents an introduction to the design, application, and maintenance of hydraulic and pneumatic systems. It features large, full-color illustrations detailing systems, components, and devices specific to industrial and commercial applications."--

This volume comprises chapters covering most of the techniques employed in modern stability analysis of nonlinear models. Techniques are introduced and employed in the context of diverse real-world problems drawn from a number of fields including, fluid and solid mechanics, electromagnetic and plasma wave propagation, mathematical ecology and mathematical biology.

The low viscosity of liquid helium makes it possible to construct compact wind tunnels that can sustain flows with extremely high Reynolds numbers; these have applications ranging from basic investigations of turbulence to practical testing of supersonic aircraft. Based on papers presented at a workshop held at the University of Oregon in October of 1989, the contributions in this volume discuss both the problems of the design of such wind tunnels and the relevant properties of helium.
