Study on the viscosity properties of bubbly oil and the static characteristics of journal bearing lubricated with bubbly oil

摘要

A new device, rotatory viscometer, for measuring viscosity of bubbly oil was proposed. Using this device, a new viscosity model, which is better than a number of existing models in many aspects was established. By the new model, a numerical method for studying the influences of bubbly oil on static characteristics of the journal bearing, which were verified by use of the remade MPV--1500 journal bearing testing machine, was developed
