Numerical models for the phenomenological study of flameless combustion

Ingeniería e Investigación, 2009
Flameless combustion is a technique which offers environmental advantages such as lower than 100 ppm NOx and CO emis- sions due to below 200 K temperature gradients. Flameless combustion also supplies higher than 70% energy efficiency.
