Some optional inputs for outwardly propagating flames:
extrapolation technique?
correction: flow, pressure, radiation?
minimum radius:
maximum radius:
sampling rate:
ignition energy:
Some aspects that might be worth considering for outwardly propagating flame experimental setup:
chamber geometry: cylindrical/spherical
radius:
diameter: (optional)
pressure release?
By the way, it is common convention to report unburned flame speeds whereas the measured flame propagation speed more closely resembles a burned flame speed and then it is converted to an unburned flame speed using the density ratio.
