Mesoscale Analysis of Hydraulics, 1st ed. 2021

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.

Weilin Xu, male, born in October 1963, is Professor, Ph.D. Winner of the National Science Fund for Distinguished Youth Scholars, the Changjiang Chair Professor, Vice President of Sichuan University and Director of the State Key Laboratory of Hydraulics and Mountain River Engineering. Professor Xu is the executive member of the council of CSHE (Chinese Society of Hydroelectric Engineering) and member of the council of CHES (Chinese Hydraulic Engineering Society). Professor Xu has mainly worked on the high dam hydraulics. He has undertaken more than 50 research projects, including key research projects supported by the National Natural Science Foundation. He has also implemented several research programs that are included in “973 Plan” and “National Sci-Tech Support Plan.” Besides, he has taken charge of many national key high dam projects. He has published over 100 papers, and he has published 4 monographs. His achievements have been applied in high dam projects such as Jinping-I Hydropower Station, Xiluodu Power Station and Pubugou Hydropower Station. Additionally, lots of prizes have been awarded to Professor Xu, which included 1 second prize of “National Award for Technological Invention” and 2 second prizes of National Award for Progress in Science and Technology.
