Advanced Experimental and Numerical Techniques for Cavitation Erosion Prediction

This book provides comprehensive coverage of both the fluid and material aspects of cavitation erosion. It details facilities and measurement techniques commonly used in cavitation erosion studies and presents various stages of cavitation damage.

This book provides a comprehensive treatment of the cavitation erosion phenomenon and state-of-the-art research in the field. It is divided into two parts. Part 1 consists of seven chapters, offering a wide range of computational and experimental approaches to cavitation erosion. It includes a general introduction to cavitation and cavitation erosion a detailed description of facilities and measurement techniques commonly used in cavitation erosion studies, an extensive presentation of various stages of cavitation damage (including incubation and mass loss) and insights into the contribution of computational methods to the analysis of both fluid and material behavior. The proposed approach is based on a detailed description of impact loads generated by collapsing cavitation bubbles and a physical analysis of the material response to these loads. Part 2 is devoted to a selection of nine papers presented at the International Workshop on Advanced Experimental and Numerical Techniques for Cavitation Erosion Prediction (Grenoble, France, 1-2 March 2011) representing the forefront of research on cavitation erosion. Innovative numerical and experimental investigations illustrate the most advanced breakthroughs in cavitation erosion research.

Comprehensive treatment of both fluid and material aspects of cavitation erosion Includes the most relevant experimental methods and computational approaches to study cavitation erosion Includes a didactic and instructive presentation that can be used as a textbook for graduate students Presents state-of-the-art research useful for engineers and researchers in the field Provides predictive techniques of cavitation damage in hydraulic machineries such as propellers and pumps Describes cavitation damage in terms of microscopic and macroscopic phenomena in solid state plasticity Offers experimental and numerical inverse method tools to estimate impulsive pressures from materials damage Includes supplementary material: sn.pub/extras
