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).
