Determination of Stretch-Corrected Laminar Burning Velocity and Selection of Accurate Analytical Model for Burned Gas Mass Fraction Using Constant Volume Method

摘要

The laminar burning velocity is an intrinsic property of a fuel-air mixture that affects many aspects of combustion behaviour. It is, for example, an important parameter for analysis and performance predictions of various SI engines. It is defined as the velocity, relative to the unburned gas, with which a planar, one-dimensional flame front travels along the normal to its surface. Laminar burning velocity values are also important for tuning and validation of chemical mechanisms.
