The main conclusion from the present study is that, the
modification done for the model of Rallis et al. [11] gives an
accurate data for the determination of the laminar burning
velocity.
However, there are some specific conclusions from the
present experimental study according to the experimental
observations and the calculations of the burning velocity
and explosion index.
(1) For the same Pi, as Ti increases Pmax decreases while
(dP/dt)max increases but the corresponding durations
for Pmax and (dP/dt)max decrease.
(2) At Pi 6 Patm, Pmax for propane is higher than that for
LPG, while at elevated pressure LPG is higher. The
peak value of (dP/dt)max for propane is 20% higher
than that for LPG.
(3) The period of inflection point of pressure record are
found to be nearly 60–75% of the maximum combustion
duration.
(4) Maximum SL for propane is nearly 455 mm/s, which
is considerably higher than that for LPG of approximate
432 mm/s.
(5) As Pressure increases, (v) decreases for both fuels, and SL
increases as (T) increases for LPG–air mixture.
(6) KG increases as Pi increases, but slightly increases as
Ti increases.
