Numerical investigation of the heterogeneous combustion processes of solid fuels [PDF]
, 2015 Two-phase computational modelling based on the Euler–Euler was developed to investigate the heterogeneous combustion processes of biomass, in the solid carbon phase, inside a newly designed combustion chamber (Model 1). A transient simulation was carried

Investigation of transition between spark ignition and controlled auto-ignition combustion in a V6 direct-injection engine with cam profile switching [PDF]
, 2008 Controlled auto-ignition (CAI) combustion, also known as Homogeneous Charge Compression Ignition (HCCI) can be achieved by trapping residuals with early exhaust valve closure in a direct fuel injection in-cylinder four-stroke gasoline engines (through ...

Mixture Temperature-Controlled combustion: a revolutionary concept for ultra-low NO$_x$ emission [PDF]
Viktor J\'ozsa: Mixture Temperature-Controlled combustion: a
revolutionary concept for ultra-low NO$_x$ emission, Fuel, 291, 120200, 2021, 2020 Mixture Temperature-Controlled (MTC) combustion is a novel concept, offering 50% reduction in NOx emission compared to V-shaped flames without a known compromise. The flame was stable up to an equivalence ratio of 0.57, which was followed by blowout as the lean flammability limit was approached.

Optical study of flow and combustion in an HCCI engine with negative valve overlap [PDF]
, 2006 One of the most widely used methods to enable Homogeneous Charge Compression Ignition (HCCI) combustion is using negative valve overlapping to trap a sufficient quantity of hot residual gas. The characteristics of air motion with specially designed valve

Numerical study of nitrogen oxides chemistry during plasma assisted combustion in a sequential combustor [PDF]
Numerical study of nitrogen oxides chemistry during plasma
assisted combustion in a sequential combustor, Combustion and Flame Volume
260, February 2024, 113206, 2023 Plasma Assisted Combustion (PAC) is a promising technology to enhance the combustion of lean mixtures prone to instabilities and flame blow-off. Although many PAC experiments demonstrated combustion enhancement, several studies report an increase in NOx emissions.

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