报告人简介:

　　Xavier Escaler is an associate professor at Department of Fluid Mechanics of Polytechnic University of Catalonia (UPC), Spain. He is a project leader in Centre for Industrial Diagnostics and Fluid Dynamics (CDIF) within the UPC. He finished his Ph. D. thesis work on cavitation erosion in the Laboratory for Hydraulic Machines (LMH) of the Swiss Federal Institute of Technology in Lausanne, which owns a high admiration as an international neutral model test stand for hydraulic machines.

　　His major research interests are cavitating flows, fluid-structure interaction and dynamic behaviour of rotating machinery. Professional experience spans the use of instrumentation for measurement of rotating machinery, signal processing and analysis techniques both for off-line and on-line.
