Hot section components life usage analyses for industrial gas turbines
Industrial gas turbines generally operate at a bit stable power levels and the hot section critical components, especially high pressure turbine blades are prone to failure due to creep. In some cases, plants are frequently shut down, thus, in addition to creep low cycle fatigue failure equally …

An experimental investigation of the conversion of NO to NO2 in a simulated gas turbine environment
… of NO₂ have been noted in stack emissions from industrial gas turbines. NO₂ formation appears to occur through the so called "HO₂ mechanism II in which NO combines with HO₂ to produce NO₂ and OH. In this study, the formation of NO₂ was investigated through computer modeling and experimental …

Experimental Investigation of Particulate Deposition on a Simulated Film-Cooled Turbine Vane Pressure Surface in a High Pressure Combustion Facility
Use of coal syngas for Integrated Gasification Combined Cycle (IGCC) industrial gas turbines introduces contaminants into the flow that can deposit onto the components of the first stage of the turbine. These deposit structures may create alterations in the cooling scheme and can erode or react …

Corrections to inter-blade-row flow measurements in axial compressors
For industrial multistage axial compressors, flow measurements in axial gaps between the blade rows are limited by mechanical constraints and the high uncertainty of the gathered data. The main factors affecting measurement uncertainties are the confined space between the blade rows, large relative …

The Effects of Porous Inert Media in a Self-Excited Thermoacoustic Instability: A Study of Heat Release and Reduced Order Modelling
… to reduce emission and fuel consumption in industrial gas turbines, lean premixed combustion is utilized but is susceptible to thermoacoustic instabilities. These instabilities occur due to an in-phase relationship between acoustic pressure and unsteady heat release in a combustor. …
