Noticeable burning velocity enhancement was observed at off-stoichiometric conditions rather than stoichiometric conditions.
Heat recirculation from the post-flame to the pre-flame is shown to be the primary mechanism for flame stabilization and burning rate enhancement in micro-channels.
However, burning velocity enhancement has not been validated to date, and hence understanding of aerosol combustion mechanisms is limited for conditions of considerable practical importance.
The maximum burning rate enhancement factor, defined as the ratio of the parameter for interacting fires to non-interacting ones, was shown to be 2.3.
Results indicate that radiation absorption by the hybrid droplet does play a role in the enhancement of burning rate.
Therefore, the enhancement in burning rate is minimal with the inclusion of nano-Al in sandwiches with smaller fine AP size, whereas the nano-aluminized sandwiches containing larger fine AP particles exhibit such enhancement.
Results show that, depending on the oscillation Reynolds number, which is a function of pressure, flow amplitude and droplet diameter, there are three mechanisms involved in the enhancement of burning rate.
"Burning schools, burning markets.
Further, using the CH4 stable carbon isotopic data (δ13C), we attribute the emission increase during 1940 1990 primarily to enhancement of biomass burning.
The effect of ozone additive on the enhancement of the burning velocity for premixed methane air flames is investigated by both experimental measurements and kinetic simulations.
Inspection of the model-predicted species profiles suggest that the enhancement of CH4 burning rates with H2 addition is driven by early H2 breakdown increasing radical production rates early in the flame zone to enhance CH4 ignition under conditions where otherwise CH4 combustion might be prone to undergo extinction.
