The main goal of this project is to design and implement a reliable testing method for the efficiency of rotational deaerators. The efficiency can be determined by monitoring the percentage of air the deaerator removes from a combined air/oil flow. The deaerators in question are used in aircraft IDG applications and thus the testing method must be able to determine efficiency at varying speeds and oil temperatures. This type of testing is rarely done in industry and so the existing testing methods are not well established. Two phase flow measurement is difficult and expensive, and this project will attempt to get data using only single phase flow measurement. Some concerns with this method arise, and two phase flow measurement options are evaluated. The measurement methods must be flexible enough to test different deaerator designs, as in the future, optimal deaerator geometry will be found.
