Combustion Characteristics and Laminar Flame Speed of Premixed Ethanol-Air Mixtures with Laser-Induced Spark Ignition [PDF]

open access: yes, 2018
Laser-induced spark-ignition (LISI) has an advanced ignition technique with a few benefits over spark ignition. In this study, flame morphology, laminar flame characteristics and combustion characteristics of premixed anhydrous ethanol and air mixtures ...

Local burning velocity in a Bunsen jet flame [PDF]

open access: yes, 2012
A PIV-based system has been set-up for the simultaneous measurement of the local burning velocity of premixed flames and the flame stretch due to the flame front curvature and the incoming flow strain rate.

Pyramidal Structures on Yttria‐Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material

open access: yesAdvanced Engineering Materials, EarlyView.
New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Cool Flame Propagation Speeds

open access: yes, 2007
Cool flames are studied at reduced-gravity in a closed, unstirred, spherical reactor to minimize complexities associated with natural convection. Under such conditions, transport is controlled by diffusive fluxes and the flames are observed to propagate ...

The Effects of Flame Stretch on Outwardly Propagating Flames

open access: yesJSME International Journal Series B, 2003
The effects of flame stretch on an outwardly propagating flame are considered experimentally for both laminar and turbulent flames. Although the thermo-diffusive mechanism caused by the flame/stretch interaction is well known for laminar flames or for weakly stretched flames, recent studies have shown that it influences the local and global flame ...
