Summary on Grant Application Form |
|
The fluid notion prevailing in the bearing chamber of an aero-engine is complex due to the presence of two fluid phases enclosed by high speed rotating walls. The presence of air and oil in a chamber with walls rotating at high speed can result in oil fires as well as the deterioration of the oil lubrication function. Conventional fluid velocity transducers are not suitable in the hostile chamber conditions; which explains the lack of data needed to optimise the function of the chamber and to validate numerical calculations.The objective is to visualise and measure non-intrusively, using advanced laser anemometry, the flow field inside the bearing chamber. The ultimate aim is to reveal the fundamental flow phenomena prevailing and recommend improvements for better engine performance.The experimental programme will be first conducted on a specially developed model scale test rig then implemented on a full-scale test rig. Particle Imaging Velocity (PIV) will be used in addition to miniature video cameras, embedded in the chamber, to provide real time images of the flow field within the chamber. The continuous monitoring of the flow will give details on the development and break-up of films on the chamber walls.
