Model constant C of turbulent NO reaction time model
Case Studies in Thermal Engineering, 2017 The NO concentration of turbulent jet flames with different fuel, jet velocity, and jet diameter are simulated with the turbulent NO reaction time model. The predicted NO profile has very good agreement with the experimental data.

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

Effects of swirl on intermittency characteristics in turbulent non-premixed flames [PDF]
, 2012 Swirl effects on velocity, mixture fraction and temperature intermittency have been analysed for turbulent methane flames using LES. The LES solves the filtered governing equations on a structured Cartesian grid using a finite volume method, with ...

Environmental Impact of Silicic Magmatism in Large Igneous Province Events
Geophysical Monograph Series, Page 133-151., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
