Effects of Flame Propagation Velocity and Turbulence Intensity on End-Gas Auto-Ignition in a Spark Ignition Gasoline Engine

Energies, 2020
Knocking is a destructive and abnormal combustion phenomenon that hinders modern spark ignition (SI) engine technologies. However, the in-depth mechanism of a single-factor influence on knocking has not been well studied.

Direct determination of burning velocity during aluminium flame propagation

Chemical Engineering Transactions, 2022
Numerical simulations are needed to model accurately the consequences of dust explosions. One key parameter for modelling the flame propagation is the burning velocity (ie the consumption rate of the reactants by the flame front).
