Course detail

Elastohydrodynamics

FSI-9EHDAcad. year: 2010/2011

The overall aim of this course is to provide students with a general and useful introduction to the main concepts and principles of elastohydrodynamic (EHD) lubrication. It is the mechanism of lubrication that describes the separation by a lubricant film between two elastic non conforming machine elements loaded against each other, and in relative motion. The course covers introduction to EHD lubrication, the fundamentals required in understanding EHD lubrication and in-depth study of selected topics related to EHD lubrication.
