Visualization of the soot formation process in the volatile flame of single coal particle using 10-kHz PAHs-PLIF, LII and LIS

open access: yesNihon Kikai Gakkai ronbunshu, 2021
Soot formation process during coal combustion is one of a key phenomenon to achieve a high-performance furnace. This is because the thermal radiation of soot influences the temperature distribution and the heat transfer process in the furnaces.

Numerical analysis of reaction-diffusion effects on species mixing rates in turbulent premixed methane-air combustion [PDF]

open access: yes, 2009
The scalar mixing time scale, a key quantity in many turbulent combustion models, is investigated for reactive scalars in premixed combustion. Direct numerical simulations (DNS) of three-dimensional, turbulent Bunsen flames with reduced methane-air ...

Forcing Pulsations by Means of a Siren for Gas Turbine Applications

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2020
A siren is a robust fast-valve that generates effective flow pulsations and powerful noise levels under well-controlled conditions. It operates under the inlet flow conditions of a gas turbine combustor.

Effect of coal mine organic aerosol on the methane/air lower explosive limit

open access: yesInternational Journal of Coal Science & Technology, 2020
Organic aerosol is formed in coal mines due to heat release and evaporation of organics from coal during the longwall operation. This frictional heating occurs when a metallic cutting bit strikes a rock.
