Course Description

This course presents a detailed and comprehensive treatment of operation 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 course focuses on:

         Fuel consumption, power output, and exhaust gas emissions

         Structural integrity and component life evaluation

         Operating loads, component deflections, rotor-to-stator rub

         Manufacturing and assembly methods, balancing of rotors

         Test verification of design parameters and fault diagnosis

         Failures arising from cyclical loads and thermal distortion

         Material requirements and selection

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 develops methods to understand the wide range of parameters and take advantage of the latest technical advances. Emphasis will be placed on controlling operating parameters, interpreting and comparing alternatives and obtaining realistic solutions.
