  • Guide To Coolant In Oil Test Methods

    Liquid cooled engines and rotating equipment use glycol based coolants because of their excellent heat transfer abilities. However, glycol based coolants are not desirable at all in lubrication oil itself – Coolant ingression to the lubricant is a particularly nasty contaminant for the variety of damage it can cause. Glycol coolants break down in the high temperature engine environment, ...

  • Rotating angled plate diffusing wave spectroscopy

    Solid–like non–ergodic samples can be difficult to study using standard single speckle diffusing wave spectroscopy as the measurement may lack requisite ensemble averaging. We demonstrate here that this required ensemble averaging can be induced by translating the speckle over the collection optics so that multiple speckles are observed over the duration of the experiment. Translation is achieved ...
