TURBO MACHINERY DESIGN AND PERFORMANCE

DESCRIPTION

This course presents a detailed and comprehensive treatment of performance and maintenance of turbo-machinery.  Starting with the fundamentals of thermodynamics and cycle design, the latest trends in development and production of many different types of turbo-machines are covered. In-depth methods to analyze and explore new operation and maintenance procedures, minimize exhaust emissions, and maximize structural integrity and operating efficiency are presented.

The ever-increasing quest for electrical and mechanical power, coupled with stricter restrictions on environmental pollutants, require exacting consideration of natural resources.  Creative technological solutions are needed to optimize operation and achieve, often times, conflicting goals.  This course teaches methods, which help one understand the wide range of parameters, as well as how to take advantage of the latest technical advances.  Emphasis is placed on controlling operating parameters, interpreting and comparing alternatives, and obtaining realistic solutions.

Specially prepared notes and the instructor’s textbook,Turbo-Machinery Dynamics: Design and Operationwill be provided to all participants on a computer disk, as well as a bound copy of the course notes.  The electronic notes and textbook are linked for instant access and in-depth study from the notes directly to the specific page of the book through electronic bookmarks.  Attendees will also receive computer codes with instructions for simulating and analyzing rotating machinery problems, parameter measurement and balancing of rotors.

YOU WILL LEARN TO
 - Describe fuel consumption, power output, and exhaust gas emissions 
 - Explain structural integrity and component life evaluation 
 - Identify operating loads, component deflections, rotor-to-stator rub 
 - Explain the process of manufacturing and assembly methods, balancing of rotors 
 - Explain the test verification of design parameters and fault diagnosis 
 - Identify failures arising from cyclical loads and thermal distortion 
 - Identify material requirements and selection

WHO SHOULD ATTEND
Design and development engineers, plant engineers, field service engineers and technical managers with product and/or project responsibility will benefit from this course. Individuals familiar with calculus and personal computers, and those with a Bachelor’s degree or equivalent work experience will have sufficient background for this course.
