A review of laminar flame speeds of hydrogen and syngas measured from propagating spherical flames
As promising alternatives to fossil fuels, hydrogen (H2) and syngas are playing important roles in the development and control of high-efficiency, low-emission engines. Achieving accurate prediction of H2-fueled combustion requires a reliable chemical mechanism which, however, still exists considerable uncertainty.

Numerical investigation of forced ignition in laminar counterflow non-premixed methane-air flames [PDF]
Simulations of forced ignition of non-premixed laminar counterflow flames are used to study the effect of strain rate on ignition success. A one dimensional calculation is performed, using detailed methane chemical kinetics and treating the spark as an ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
