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

Oxygen combustion of CH4-CO2 mixture in a small-scale counterflow burner
Journal of Thermal Science and Technology, 2018 Oxygen combustion of CH4-CO2 mixture in a small-scale counterflow burner was studied. A diffusion flame was stabilized in the gap between opposed ports ejecting fuel and oxygen gases, and its thickness which depended on the gap distance between burner ...

Influences of stretch and curvature on the temperature of stretched cylindrical diffusion flames
Journal of Thermal Science and Technology, 2016 The structure of a counterflow-type cylindrical diffusion flame was studied experimentally to determine the effect of stretch and curvature. The cylindrical flame used in this study had a concave curvature with respect to the fuel stream.

Flame sheet starting estimates for counterflow diffusion flame problems
Journal of Computational Physics, 1987 The authors develop a flame sheet starting procedure for the numerical modelling of laminar counterflow diffusion flame problems. The model couples the equations of mass and tangential momentum with a Shvab- Zeldovich equation to provide estimates for the mass flux in the transverse direction, the similarity function, the temperature and the stable ...
