# Nitromethane the simplest nitroparaffin fuel is

When considering a spherical outwardly expanding flame, the previous equation can be simplified to the following expression:equation(3)K=2rfdrfdt

The unstretched laminar flame velocity Vs0 MLN9708 obtained from the non-linear model. To determine the fundamental unstretched laminar burning velocity SL0, the effect of the expansion factor (ρb/ρu) has to be considered:equation(4)SL0=ρbρuVs0where ρb and ρu are the densities of the burned and the unburned gases respectively. These densities were calculated using the EQUIL code [12] from CHEMKIN package.
