Laminar Velocity

Computational studies of the laminar burning velocity of a producer gas and air mixture under typical engine conditions

From the article:

This paper discusses computational results concerning the laminar burning velocity of a biomass-derived producer gas and air mixture at pressures and temperatures typical of the unburned mixture in a reciprocating engine. The computations are based on solving conservation equations describing laminar one-dimensional, multi-component, chemically reacting, and ideal gas mixtures that have been formulated by earlier researchers. Based on a number of calculations at varying initial pressures and temperatures, and equivalence ratios, an expression for estimating the laminar burning velocity with the recycled gas mass fraction has been obtained. Also, the effect of varying amounts of recycled gas on the burning velocity has been determined. These data on laminar burning velocities will be useful in predicting the burnrate in a sparkignition (SI) engine fuelled with a producer gas and air mixture.
