WebWe would like to show you a description here but the site won’t allow us. WebLaminar flame speed is defined as the propagation rate of the normal flame front relative to the unburned mixture. It is an important property for a premixed flame as it embodies the fundamental information of diffusivity, reactivity, and exothermicity of the combustible hydrocarbon mixture.
WebIn normal combustion, this flame front moves throughout the fuel/air mixture at a rate characteristic for the particular mixture. Pressure rises smoothly to a peak, as nearly all the available fuel is consumed, then pressure falls as the piston descends.
