Research and Development on Coatings and Paints for Geothermal Environments: A Review
Advanced Materials Technologies, Volume 8, Issue 18, September 25, 2023., 2023 Geothermal power production, by harnessing the natural heat in the earth's crust, provides clean energy, with year‐round availability. However, corrosion, erosion, and scaling of power plant components can hinder energy production. In his review paper, the first of its kind since 1980, a detailed overview of research studies on coatings developed to ...

Applications in Energy and Combustion Science, 2023 Molybdenum-oxide nanoplates are grown directly from the surface of molybdenum substrates using a catalyst-free flame synthesis technique. To investigate the effects of oxidizing routes, e.g., from gas-phase O2, H2O, and CO2 as reactants, on the growth ...

Study on combustion performance of microgas turbine combustor with different fuels
Energy Science &Engineering, Volume 11, Issue 7, Page 2642-2653, July 2023., 2023 A low‐pollution single‐tube microgas turbine burner using different gas fuels is studied. The combustion performance and pollutant generation characteristics of two landfill gases and natural gas were tested in a single‐head burner. Abstract A low‐pollution single‐tube microgas turbine combustor using different gas fuels was studied.

International Journal of Energy Research, Volume 2023, Issue 1, 2023., 2023 Extinction limits and flame microstructures of CH4 versus air (N2/O2) counterflow diffusion flames with additional CO2 to oxidizer stream under various pressure conditions were numerically investigated by a proposed decoupled strategy. The chemical and thermal effects of CO2 addition were isolated from the synergistic effect on extinction limits and ...

Journal of Geophysical Research: Atmospheres, Volume 127, Issue 22, 27 November 2022., 2022 Abstract Soot particles are one of the major aerosol components (in particle number concentration) in the troposphere and can impact cirrus formation. Depending on their physicochemical properties, soot particles can nucleate ice in the cirrus regime via pore condensation and freezing (PCF) at a lower ice saturation threshold than that of the ...

International Journal for Numerical Methods in Fluids, Volume 94, Issue 4, Page 316-345, April 2022., 2022 We present a fully coupled discontinuous Galerkin solver in a low‐Mach framework using a one‐step kinetic model with variable parameters. The solution of the discretized system is done with a globalized Newton method. The solution of the flame sheet problem allows us to obtain adequate initial conditions for the solution of the fully coupled problem. A

Journal of Combustion, Volume 2022, Issue 1, 2022., 2022 Lean premixed (LPM) combustion processes are of increased interest to the gas turbine industry due to their reduction in harmful emissions. These processes are susceptible to thermoacoustic instabilities, which are produced when energy added by an in‐phase relationship between unsteady heat release and acoustic pressure is greater than energy ...
