Mesoscale Analysis Of Hydraulics

Introduction.- Mesoscale analysis of cavitation and cavitation erosion.- Mesoscale analysis of aeration for cavitation erosion protection.- Mesoscale analysis of air-water two-phase flow.- Mesoscale analysis of flood discharge and energy dissipation

This open access book presents a series of complicated hydraulic phenomena and related mechanism of high-speed flows in head-head dam. According to the basic hydraulic theory, detailed experiments and numerical simulations, microscopic scale analysis on cavitation bubbles, air bubbles, turbulent eddy vortices and sand grains are examined systemically. These investigations on microscopic fluid mechanics, including cavitation erosion, aeration protection, air–water flow, energy dissipation and river-bed scouring, allow a deep understanding of hydraulics in high-head dams. This book provides reference for designers and researchers in hydraulic engineering, environment engineering and fluid mechanics.

The swelling of concrete is a major concern for the owners and operators of dams and hydraulic structures. Faced with irreversible movement of their dams or with observations of cracking processes, operators need to explain the phenomena observed in order to justify safety conditions and in some cases to plan remedial works. Over the last 20 years, active research has been carried out in the field, resulting in practical results in phenomena interpretation and dam modeling. At the same time, an increasing number of affected dams have undergone safety re-evaluations and in some cases remedial work. Several of them have been removed altogether. Although it remains difficult to establish a “state of the art” in this domain due to the rapidly changing context, regular international exchanges in the field appear fruitful and necessary. Following on from previous conferences in the field organized by Robin Charlwood, former President of the ICOLD Concrete Committee, the initiative was taken by EDF and Toulouse University-LMDC to organize a workshop to provide a new opportunity for sharing experience. The aim of this workshop is to assemble active researchers, leading engineers, and experts from the practicing community and administration interested directly or indirectly in concrete swelling effects in dams and hydraulic structures. All types of chemical expansion phenomena, including those due to alkali aggregate reactions and those due to ettringite formation, are addressed. These proceedings include 24 papers written by experts renowned in their field, illustrating the need to progress with interdisciplinary approaches.

Hydraulic research is developing beyond the borders of traditional civil engineering to meet increasing demands in natural hazards, structural safety assessment and also environmental research. Hydraulic Engineering III contains 62 technical papers from the 3rd Technical Conference on Hydraulic Engineering (CHE 2014, Hong Kong, 13-14 December 2014)

The International Conference on Civil, Architectural and Hydraulic Engineering series provides a forum for exchange of ideas and enhancing mutual understanding between scientists, engineers, policymakers and experts in these engineering fields. This book contains peer-reviewed contributions from many experts representing industry and academic es

Synoptic meteorology, the study of large-scale weather systems and forecasting using observation, and dynamic meteorology, the study of the laws of physics involved in air movement, are treated in this major new text in two volumes. The author, a meteorologist noted for his research on tornadoes and severe storms, based his work on material he has taught for the past 14 years at the University of Oklahoma. There are no modern texts on the topic. Volume II covers the formation, motion and climatology of extratropical weather systems in the context of the quasigeostrophic theory and "IPV" thinking, the formation and structure of fronts and jets, applications of semigeostrophic theory, and the observed structure and dynamics of precipitation systems in midlatitudes.
