Rotating blade and disk fatigue failures cause a fairly small percentage of machine shutdowns, but can require extensive repairs and downtime. This tutorial focuses on steam turbines, centrifugal compressors, and axial compressors primarily for refineries and process plants. For steam turbines, axial compressors, and openimpeller centrifugal compressors, the main concern is resonance giving bla...

Rotating Machinery and Measurement Technology Section at Southwest Research Institute, in San Antonio, Texas. His research interests are in the areas of turbomachinery aerothermal fluid dynamics, process system analysis, energy management, advanced thermodynamic cycles, instrumentation and measurement, and combustion technology. He is widely experienced in performance prediction, off-design fun...

Gas turbines play an important role in supplying power for the country especially in peak electricity load. The main disadvantages are the turbines, they produce large changes are a result of climate change. However, in times of peak electricity grid and at the same time warm months, can produce gas turbines under the effect of ambient temperature, the amount of reduced considerably. The method...

Performance of a gas turbine mainly depends on the inlet air temperature. The power output of a gas turbine depends on the flow of mass through it. This is precisely the reason why on hot days, when air is less dense, power output falls. The objective here is to assess the advanced systems applied in reducing the gas turbine intake air temperature and examine the merits from integration of the ...

The University of Texas at Austin is well known for its quality of education and research. In order to maintain a high standard of education, the uninterrupted and cost-effective power, steam and cooling supply plays an important role. To meet this need, the University of Texas at Austin – Utilities and Energy Management Department decided to adopt an innovative predictive maintenance based sol...

Concept of Safe diagram was introduced 30 years ago (Singh and Schiffer, 1982) for the analysis of the vibration characteristics of packeted bladed disc for steam turbines. A detailed description of Safe diagram for steam turbine blades was presented 25 years ago in the 17 th Turbo Symposium (Singh et. el, 1988). Since that time it has found application in the design and failure analysis of man...
