Refined Flow Modelling And Turbulence Measurements

Offers a review of numerical modelling in fluid dynamics for the purpose of industrial or environmental studies. The book is divided in 9 sections: modelling turbulent flows; numerical techniques in fluid dynamics; refined experiments aimed at the validation of numerical models; flows with heat transfer; two-phase flows; flows with large density variations and reacting flows; flows of surface water and free surface flow modelling; stratified flows and flows around structures; flows in turbomachines, pipes, and boundary layers.

This book is an essential reference for engineers and scientists working in the field of turbulence. It covers a variety of applications, such as: turbulence measurements; mathematical and numerical modeling of turbulence; thermal hydraulics; applications for civil, mechanical and nuclear engineering; environmental fluid mechanics; river and open channel flows; coastal problems; ground water.

Papers presented at the Fourth International Symposium on Refined Flow Modelling and Turbulence Measurements, held in Wuhan, P.R. China, September 1990, discuss modeling in turbulent flows and heat transfer; progress in numerical techniques; dispersion, stratified flow in atmospheric and water environments; fundamental theory of turbulence; thermal hydraulics and buoyant jets; flows in rivers and open channels; multiphase flow; unsteady flow and wave motion; and turbulent flow measurements and simulations.

The aim of this book is to give, within a single volume, an introduction to the fields of turbulence modelling and transition-to-turbulence prediction, and to provide the physical background for today's modelling approaches in these problem areas as well as giving a flavour of advanced use of prediction methods. Turbulence modelling approaches, ranging from single-point models based on the eddy-viscosity concept and the Reynolds stress transport equations (Chapters 3,4,5), to large-eddy simulation (LES) techniques (Ch. 7), are covered. The foundations of hydrodynamical stability and transition are presented (Ch. 2) along with transition prediction methods based on single-point closures (Ch. 6), LES techniques (Ch. 7) and the parabolized stability equations (Ch. 8). The book addresses engineers and researchers, in industry or academia, who are entering into the fields of turbulence or transition modelling research or need to apply turbulence or transition prediction methods in their work.

First published in 1992, this is the second of two volumes on recent advances in the field of hydraulic and environmental modelling, with invited and refereed contributions from an international group of engineers, scientists and planners involved in application, research and development. It covers the estuarine and river waters with parts devoted to: flow processes; flow modelling; salinity intrusion modelling; water quality modelling; sediment transport modelling; expert systems. The first volume covers coastal waters. With the continually increasing interest in the development and application of numerical hydraulic models, their value is especially evident as tools of design and management for flow, pollutant and sediment transport simulation studies in various environments. The readership includes practising engineers and scientists in the water industry, consulting engineers, water companies and the NRA and other government departments, university and polytechnic libraries, staff and students and all other members of the water engineering profession.
