The Response of a Conical Laminar Premixed Flame to Equivalence Ratio Oscillations in Rich Conditions

open access: yesJournal of Thermal Science and Technology, 2013
Responses of conical premixed methane/air mixture flames with equivalence ratio oscillations were numerically investigated at three different oscillation frequency regimes; low, medium and high (10, 50 and 150 s-1) under a rich condition.

Laser ignition of iso-octane air aerosols [PDF]

open access: yes, 2008
Iso-octane aerosols in air have been ignited with a focused Nd:YAG laser at pressures and temperatures of 100kPa and 270K and imaged using schlieren photography. The aerosol was generated using the Wilson cloud chamber technique.

Instabilities and soot formation in high-pressure, rich, iso-octane-air explosion flames - 1. Dynamical structure [PDF]

open access: yes, 2007
Simultaneous OH planar laser-induced fluorescence (PLIF) and Rayleigh scattering measurements have been performed on 2-bar rich iso-octane–air explosion flames obtained in the optically accessible Leeds combustion bomb.

Effects of each operating condition on the maximum pressure in an imploding detonation apparatus with a pre-combustion chamber

open access: yesJournal of Thermal Science and Technology, 2015
Imploding detonations can generate ultra-high pressures at their implosion centers. In this basic study, we measured the maximum pressure in an imploding detonation apparatus with a pre-combustion chamber.

Robust Localization of the Best Error with Finite Elements in the Reaction-Diffusion Norm [PDF]

open access: yes, 2014
We consider the approximation in the reaction-diffusion norm with continuous finite elements and prove that the best error is equivalent to a sum of the local best errors on pairs of elements.
