Honeycomb Seal Effect on Rotor Response to Unbalance
(Texas A&M University. Turbomachinery Laboratories, 2014)
High pressure centrifugal compressors are often equipped with honeycomb seal on balance drum in order to optimize rotordynamic stability. In very high pressures applications (>200 bar) the direct stiffness and damping of ...
Axial Thrust in High Pressure Centrifugal Compressors: Description of a Calculation Model Validated by Experimental Data from Full Load Test
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2015)
The residual axial thrust acting on the rotor of a centrifugal compressor is the result of the non-uniform pressure distribution on the surfaces in contact with the process gas, plus the differential pressure acting on the ...
Optimization of Swirl Brake Design and Assessment of Its Stabilizing Effect on Compressor Rotordynamic Performance
(Texas A&M University. Turbomachinery Laboratories, 2014)
The rotordynamic stability of high pressure compressors is strongly affected by the aerodynamic effects induced by the gas flow through rotor-stator seals. In particular the tangential velocity (swirl) of the gas flowing ...
Effect Of Relative Journal Bearing And Honeycomb Seal Direct Stiffness On Radial Synchronous Vibrations Of High-Pressure Centrifugal Compressors
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
High pressure compressors are commonly equipped with honeycomb seal on the balance piston, as an effective mean to improve the rotordynamic stability of the system. The gas leakage flow across the honeycomb seal clearance ...
