About Tutorials

A Tutorial is a mini short course/workshop. It is a teaching process. Some tutorial speakers actually bring equipment to the meeting, so the participants get hands-on instruction.
Tutorials are scheduled in one and one-half hour blocks, with 30 to 45 minutes of the time devoted to questions and answers.
Tutorials are presented twice and are published in the symposium Proceedings.

Below is the list of tutorials that will be presented at the 37th Turbomachinery Symposium:

Tutorial 1: Rotordynamic Design Audits of AMB Supported Machinery

Tuesday, September 9, 2:00-3:30, Room 360A
Wednesday, September 10, 8:30-10:00, Room 360A

Presenters:
Erik E. Swanson, Xdot Engineering and Analysis, Charlottesville, VA, Eric H. Maslen, University of Virginia, Charlottesville, VA, Guoxin Li, and C. Hunter Cloud, BRG Machinery Consulting, Charlottesville, VA

This tutorial provides an overview and discussion of active magnetic bearing (AMB) systems from the perspective of performing a rotordynamic design audit on an AMB supported rotor. Relevant standards are reviewed, and an example audit is performed on an existing machine.

Tutorial 2: The Synchronous Rotor Instability Phenomenon (Morton Effect)

Tuesday, September 9, 8:45-10:15, Room 360A
Wednesday, September 10, 2:00-3:30, Room 360A

Presenter:
Frits M. de Jongh, TurboCare B.V., Hengelo, The Netherlands

This paper covers the rotordynamic synchronous instability phenomenon nowadays better know as the "Morton effect." In addition to an elementary description of the phenomenon, it shows an overview of literature published on this subject and includes various case studies with pragmatic solutions to cure unstable synchronous rotor behavior.

Tutorial 3: Emerging Advanced Technologies to Assess Reliability of Industrial Steam Turbine Blade Design

Tuesday, September 9, 10:30-12:00, Room 360A
Wednesday, September 10, 10:30-12:00, Room 360A

Presenters:
Murari Singh, GE Oil & Gas, Bethlehem, PA, and Michael Drosjack, Shell Global Solutions (US) Inc., Houston, TX

Tutorial 4: A Review of Aerodynamically Induced Forces Acting on Centrifugal Compressors, and Resulting Vibration Characteristics of Rotors

Tuesday, September 9, 10:30-12:00, Room 360C
Wednesday, September 10, 10:30-12:00, Room 360CF

Presenters:
Jim Sorokes and Tom Soulas, Dresser-Rand Co., Olean, NY

Tutorial 5: Selection of Materials and Material Related Processes for Centrifugal Compressors and Steam Turbines in the Oil and Petrochemical Industry

Tuesday, September 9, 2:00-3:30, Room 360C
Wednesday, September 10, 8:30-10:00, Room 360CF

Presenters:
Phillip Dowson, Derrick Bauer, and Scot Laney, Elliott Co., Jeannette, PA

This paper is intended to provide a review of the various materials used in the construction of centrifugal compressors and steam turbines, as well as provide a basis for understanding the reasoning behind the material choice. Components discussed are compressor impellers, shafts, and casings and steam turbine rotors, blades, casings, and bolting. Material choices related to repairs and the application of coatings will also be discussed.

Tutorial 6: Steam Turbine Corrosion and Deposits -- Problems and Solutions

Tuesday, September 9, 8:45-10:15, Room 360C
Wednesday, September 10, 2:00-3:30, Room 360CF

Presenters:
Otakar Jonas and Lee Machemer, Jonas, Inc., Wilmington, DE

This tutorial paper discusses the basics of corrosion, steam, and deposit chemistry, and turbine and steam cycle design and operation -- as they relate to steam turbine problems and problem solutions.
