Sommario/riassunto

This book gives a systematic exposition of abrasive erosion and corrosion of hydraulic machinery in both theory and engineering practice, and is the first comprehensive volume to cover this area in depth.  All the important subjects are discussed including fundamentals, calculation, analysis and numerical simulation of liquid-solid flow design, erosion-resistant materials, interaction between cavitation and abrasive erosion, and corrosion of hydraulic machinery. <br><i>Contents:</i><ul><li>Fundamentals of Hydroabrasive Erosion Theory <i>(V Y Karelin et al.)</i></li><li>Calculation of Hydrauli
