| Scope of work: |
Design of Highly Efficient Bearing Compartments
• Identify a test rig facility for determining the parasitic losses associated with churning and inefficient scavenging in a simulated turbine engine bearing compartment.
• Analyze the rotor dynamics of the test configuration including the drive and test section. Insure response is acceptable over the range of intended operating conditions. Desired operating speeds would range from 20,000 to 30,000 rpm. If the test equipment were capable of far less, that is OK . In that case, design the rig for the speed range at which you could safely conduct testing.
• Create solid models of candidate compartment designs.
• Create a CFD model in Fluent for each design in order to predict the scavenge efficiency of candidate compartment configurations over a range of operating conditions.
• Fabricate the design showing the greatest overall performance.
• Test the design in the test rig to measure actual scavenge efficiency (power loss) over the rig operating speed range.
• Correlate the analytical models to the test data.
• Predict and measure the two-phase pressure drop characteristics of several candidate scavenge line configurations.
Correlate the predictions for the two-phase pressure drops to the test data. |
