Natural Gas Overhung Pipeline Compressor Rotordynamic Design, Test Validation, and Consideration of Morton Effect

Available to Purchase

Wei Li, Christopher Braman, Hiroki Hatori, Manish Thorat, Brian Pettinato
Proc. ASME. GT2024, Volume 9: Manufacturing Materials and Metallurgy; Microturbines, Turbochargers, and Small Turbomachines; Oil & Gas Applications; Steam Turbine, V009T19A017, June 24–28, 2024
Publisher: American Society of Mechanical Engineers
Paper No: GT2024-125936
https://doi.org/10.1115/GT2024-125936
... Abstract This study examines a natural gas pipeline compressor design and its potential for “Morton effect” instability. The compressor is designed to utilize a rotor with two tandem stages arranged in an overhung configuration. An overhung rotor design allows for increased compressor...

Measured and Predicted Temperature Differentials Within a Rotor at a Tilting-Pad-Journal Bearing Associated With the Morton Effect

Available to Purchase

Chris D. Kulhanek, Seth Cunningham, Hector A. Delgado, Jeff Moore, Justin R. Hollingsworth
Proc. ASME. GT2022, Volume 8B: Structures and Dynamics — Probabilistic Methods; Rotordynamics; Structural Mechanics and Vibration, V08BT26A015, June 13–17, 2022
Publisher: American Society of Mechanical Engineers
Paper No: GT2022-83237
https://doi.org/10.1115/GT2022-83237
... Abstract The current work shows the implementation of a high-speed turbomachinery test rig to measure vibration and internal shaft temperature differentials at a journal bearing for a rotor system designed to induce the Morton effect rotordynamic phenomenon. The vibration and shaft temperature...

Morton Effect Calculation and Analysis of Shop Test Results for Single-Shaft Multistage Centrifugal Compressors

Available to Purchase

Naohiko Takahashi, Yohei Magara, Makoto Hemmi, Motoki Sato
Proc. ASME. GT2022, Volume 8B: Structures and Dynamics — Probabilistic Methods; Rotordynamics; Structural Mechanics and Vibration, V08BT26A006, June 13–17, 2022

... in vibration due to the Morton Effect. The Morton Effect is a thermal bending vibration caused by the non-uniformity of the oil film temperature of the bearing, and many troubles have been reported in overhung rotors. However, there are few reports of the Morton Effect in single-shaft multistage compressors...

Squeeze Film Damper Suppression of Thermal Bow: Morton Effect Instability

Available to Purchase

Dongil Shin, Alan B. Palazzolo, Xiaomeng Tong
Proc. ASME. GT2020, Volume 10B: Structures and Dynamics, V10BT29A008, September 21–25, 2020
Publisher: American Society of Mechanical Engineers
Paper No: GT2020-14825
https://doi.org/10.1115/GT2020-14825
... Abstract The Morton Effect (ME) is a synchronous vibration problem in turbomachinery caused by the non-uniform viscous heating around the journal circumference, and its resultant thermal bow and ensuing synchronous vibration. This paper treats the unconventional application of the SFD...
