Local flame structure and turbulent burning velocity by joint PLIF imaging

Local flame structure and turbulent burning velocity by joint PLIF imaging
In this study, we have examined local flame structure by joint PLIF imaging, using simultaneous HCHO/OH-PLIF and orthogonal OH-PLIF measurements. By considering the degree of flame wrinkling, three-dimensional flame surface area is obtained from 2D images.

Validation of a new level set approach in the counter flow premixed flame

Journal of Thermal Science and Technology, 2014
The flamelet model based on the concept of local flame speed S*is newly developed to describe a premixed flame with a finite thickness when defining G as the non-dimensional temperature.

Modelling and Numerical Simulation of Dual Fuel Lean Flames Using Local Burning Velocity and Critical Chemical Timescale [PDF]

SAE International Journal of Engines, 2019
<div>Addition of hydrogen to hydrocarbons in premixed turbulent combustion is of technological interest due to their increased reactivity, flame stability and extended lean extinction limits. However, such flames are a challenge to reaction modelling, especially as the strong preferential diffusion effects modify the physical processes, which are

Testing of NH3/H2 and NH3/syngas combustion mechanisms using a large amount of experimental data

Applications in Energy and Combustion Science, 2023
A possible solution to improve the combustion properties of ammonia is to blend it with other fuels. Two of the most usually used co-fuels are hydrogen and syngas (H2/CO). To investigate the chemistry of the co-combustion with these fuels, a large amount
