... of the injected liquid phase. Water droplets erosion is handled by using a semi-empirical model developed by the authors. In each simulation 504000 parcels have been tracked, providing statistically reliable predictions. To simulate long-term evolution of the washing process, a discrete mesh morphing technique...

Proc. ASME. GT2022, Volume 7: Industrial and Cogeneration; Manufacturing Materials and Metallurgy; Microturbines, Turbochargers, and Small Turbomachines; Oil & Gas Applications, V007T17A003, June 13–17, 2022
Publisher: American Society of Mechanical Engineers
Paper No: GT2022-80263
... Abstract Gas turbine compressor blades operating with air inlet fogging can suffer from Water Droplet Erosion (WDE). WDE can also affect the last rows of steam turbines where expanding steam produces water condensation, especially under start-up and low load conditions. WDE damages the blades...

... energy and erosion. The numerical simulation is performed with ANSYS Fluent in which a new water droplet erosion model, introduced in previous papers, is here included as a User Defined Function. The discussion provides useful information for prescribing the injector characteristics and the water washing...

Publisher: American Society of Mechanical Engineers
Paper No: GT2020-16262
... Abstract In order to study the effect of initial surface roughness on water droplet erosion resistance of last stage blade substrate of steam turbine, eight 17-4PH samples were grounded and velvet polished by different mesh metallographic sandpaper to establish sample with different initial...
