Our industrial partner, GasTOPS Ltd., is a Canadian leader in machinery operation monitoring technologies. They have an interest in developing a new in-line oil monitor capable of detecting the remaining useful life of a lubricating oil. The requires an accurate model of the relationship between oil operating conditions and detectable levels of degradation by-products. While it is known qualitatively that high shear stresses, temperatures and pressures all play interdependent roles in lubricating oil breakdown, the quantitative relationship between stress levels and by-product formation rates is not understood. In this project, we will develop this understanding through a combination of theoretical calculations and experiments. The end goal will be a "engineering" model of the relationship between oil stress history and by-product formation, which will be validated with the help of the experimental data.

我们的工业合作伙伴GasTOPS Ltd.是加拿大机械运行监控技术的领导者。 他们有兴趣开发一种新的在线油监测器，能够检测润滑油的剩余使用寿命。 这就需要一个精确的模型来描述石油操作条件和降解副产品的可检测水平之间的关系。 虽然定性地知道高剪切应力、温度和压力在润滑油分解中都起相互依赖的作用，但应力水平和副产物形成速率之间的定量关系尚不清楚。 在这个项目中，我们将通过理论计算和实验相结合来发展这种理解。 最终目标将是建立一个石油应力历史和副产品形成之间关系的“工程”模型，该模型将在实验数据的帮助下得到验证。
