Turbulent and Stable/Unstable Laminar Burning Velocity Measurements from Outwardly Propagating Spherical Hydrogen-Air Flames at Elevated Pressures

Journal of Thermal Science and Technology, 2006
The laminar burning velocity of pre-mixed hydrogen-air mixtures was measured in a fan stirred combustion bomb. Unstretched laminar burning velocities and Markstein lengths were obtained at 0.10MPa for equivalence ratios of 0.4, 0.6, 0.8 and 1.0 using ...

The Influence of Intrinsic Instability on the Flame Velocity of Premixed Flames.

Journal of the Japan Society for Aeronautical and Space Sciences, 2000
The influence of intrinsic instability on the flame velocity is studied by two-and three-dimensional, unsteady calculations of reactive flows, which are based on the compressible Navier-Stokes equation. We consider three basic types of phenomena which are responsible for the intrinsic instability of premixed flames, i.

Modulation of Local Environment for Selective Bicarbonate Conversion to Multi‐Carbon Products

Advanced Energy Materials, EarlyView.
Highly porous Cu electrode partially coated with an ionomer/carbon composite enables efficient conversion of bicarbonate to multi‐carbon products. By regulating the local reaction microenvironment, this strategy overcomes selectivity and reaction‐rate limitations, achieving Faradaic efficiencies of 43% for ethylene and 60% for total multi‐carbon ...
