Lubricant foaming simulation

How to reduce oil aeration in gearboxes and motors using digital models

Timetable: 10:00 - 11:00 a.m. CET time
Speaker: Michele Merelli
Language: English

Lubricant foaming in gearboxes and motors can reduce lubrication efficiency, increase power losses and cause problems with the suction pump and lubricant circuit. This is an important issue above all for electric drives with high speed rotating gears.

Foaming is a complex physical phenomenon related both to the chemical properties of the fluid and to the air-liquid interaction at the free surface.

The meshless CFD Particleworks has specific models to simulate oil foaming in gearboxes and engines. The models have been developed and validated in collaboration with automotive and lubricant companies.

This webinar will introduce the basics of the oil foaming models available in Particleworks and give practical examples of how the models can help reduce lubricant foaming in gearbox and engine design process.
