On the project

Cílem projektu je vyvinout experimentální přístup ke studiu toku tekutin ve vysoce zatížených kontaktech těles. Tento přístup je založen na detekci pohybu unášených částic a využívá optický simulátor bodového kontaktu. Přístup bude použit pro objasnění jevů vyskytujících se v EHD kontaktech

Description in English
The goal is to develop an experimental approach to the study of through-thickness fluid flow in thin-film lubricated non-conformal contacts.The approach is based on particle tracking velocimetry and ball-on-disk test rig and will be applied to the research of dimple phenomena in EHL

Keywords
