Coherent Anti-Stokes Raman Spectroscopy (CARS) Applied in Combustion Probing

\Ye have applied Coherent Anti-Stokes Raman Spectroscopy (CARS) for monitoring of a variety of important molecules in combustion media. A survey of different CARS techniques ranging from simple, scanning measurements of major species like N , to single-pulse, broad-band arraydetector registration of less abundant species is made. The CARS, BOXCARS and folded BOXCARS approaches were used observi...

Quenching and Propagation of Combustion without Ignition Temperature Cutoff

We study a reaction-diffusion equation in the cylinder Ω = R×T, with combustion-type reaction term without ignition temperature cutoff, and in the presence of a periodic flow. We show that if the reaction function decays as a power of T larger than three as T → 0 and the initial datum is small, then the flame is extinguished — the solution quenches. If, on the other hand, the power of decay is ...

Hybrid cars now, fuel cell cars later.

We compare the energy efficiency of hybrid and fuel cell vehicles as well as conventional internal combustion engines. Our analysis indicates that fuel cell vehicles using hydrogen from fossil fuels offer no significant energy efficiency advantage over hybrid vehicles operating in an urban drive cycle. We conclude that priority should be placed on hybrid vehicles by industry and government.
