Investigation on weakly curved counterflow diffusion flames at infinitely fast chemistry
We investigate the behavior of a counterflow diffusion flame subject to a flow field comprising of a first order potential flow superimposed on a weak second order correction to the potential flow. An Arrhenius one-step irreversible reaction model at infinite Damkohler number and constant density …

Studies on counterflow diffusion flames
Certain aspects of counterflow diffusion flames are addressed in the context of one-step Arrhenius-type global chemical reaction. The general Large-activation-energy asymptotic theory for diffusion flames is first revised and then applied to one dimensional counterflow diffusion flames with finite …

Experimental determination of the flow field velocity and strain rate in a laminar opposed flow H₂/air diffusion flame, via laser doppler anemometry
… investigation of an opposed flow hydrogen-air diffusion flame was conducted. The purpose was to experimentally determine the flow field velocity and corresponding strain rate under different operating flow conditions. An axisymmetric opposed jet burner was employed in this experiment where air …

An Experimental Investigation of JP-7 and n-Heptane Extinction Limits in an Opposed Jet Burner
… by the maximum global strain rate on a laminar, counterflow, non-premixed flame. The extinction limit relates to the ability to maintain combustor operation, and the extinction limit data for pure fuel versus air systems provide a relative reactivity scale for use in the design of flame holders. …

Structure and stabilization of cryogenic spray flames
… simulations requires a knowledge of the flame structure, particularly of the region near the fuel injectors. These practical considerations motivate this investigation. As well as discussion on the overall flame shape under subcritical and supercritical conditions, two aspects are given …

High order numerical methods applied to the analysis of transport phenomena in combustion
… Through numerical solutions of the convection-diffusion operator and the wave operator it is shown, that this new family of finite difference methods achieves numerically stable solutions for any degree q < N and that these solutions present correct transient behaviours. This has motivated the …
