Original abstract
The mechanical efficiency of rotating machines is continuously increased due to improved rotor-bearing system designs. However, research activities are also gradually focusing on non-traditional sources of loss, such as frictional losses due to rotor-fluid surface interaction. The main analysis tools used are computational fluid dynamics, which evaluates the fluid flow in a lubrication system and the effect on rotating rotor walls, and analytical-empirical description of the rotating turbulent fluid flow around rotating elementary bodies. The results will allow further improvement of mechanical efficiency without increased manufacturing costs.
