Summary on Grant Application Form |
|
The research programme will use computational fluid dynamics techniques to perform a thermohydrodynamic analysis of a stationary bearing, an oscillating lubricant film, and an orbiting and rotating journal. The resulting dynamic thermal equilibrium will enable an assessment to be made of the thermal state of the journal. In particular, the steady component temperature differential across the journal will determine the bend which can develop in a rotor at a position local to the bearing. It follows that the unbalance condition of the rotor will change and the basic mechanism of the bend development is that of a closed loop system. The research programme will therefore investigate the stability and response of the rotor thermal bend using classical methods. A computer program will be developed for this purpose to enable any rotor dynamic system to be assess. The CFD analysis will be performed for a range of bearing designs and the rotor thermal bend assessment will be determined for a generic rotor dynamic system. This work will have particular relevance in high speed rotating machinery applications, using hydrodynamic bearings, when designing for safe running.
