Simulation of hydrogen auto-ignition in a turbulent co-flow of heated air with LES and CMC approach [PDF]
, 2011 Large-Eddy Simulations (LES) with the first order Conditional Moment Closure (CMC) approach of a nitrogen-diluted hydrogen jet, igniting in a turbulent co-flowing hot air stream, are discussed. A detailed mechanism (nine species, 19 reactions) is used to

Formation of Turbulent Eddies in Jet Diifusion Flames.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1993 The transition from laminar to turbulent modes of an ethylene jet flame was investigated using two-dimensional instantaneous photography of turbulent eddies, by means of a laser-light sheeting method. Observations were made for the eddies around the break point in the fuel flow and the flame. The results show that in the laminar region the fuel flow is

Applications in Energy and Combustion Science, 2023 Flame spray pyrolysis (FSP) is a technique for the synthesis of metal oxide nanoparticles by combusting precursor solutions in a spray flame. The combustion of certain precursor solutions is known to lead to severe droplet disruptions (μ-explosions) in ...

Theoretical Analysis of Nitric Oxide Production in a Methane/Air Turbulent Diffusion Flame [PDF]
, 1980 The coherent flame model is applied to the methane-air turbulent diffusion flame with the objective of describing the production of nitric oxide. The example of a circular jet of methane discharging into a stationary air atmosphere is used to illustrate ...

Thermal Calculations for Co‐Firing of Hydrogen/Ammonia and Coal in 660‐MW Coal‐Fired Boilers
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT To achieve a clean energy transition under the dual carbon goals, blending hydrogen/ammonia into pulverized coal boilers represents a key technological pathway. Different hydrogen/ammonia co‐firing ratios (5%–50%) are investigated for their impact on the thermodynamic characteristics of 660‐MW supercritical boiler at 100% and 20% boiler ...
