Upward Turbulent Flame Spread [PDF]
Fire Safety Science, 1986 Mechanisms and rates of upward spread of turbulent flames along thermally thick vertical sheets are considered for both noncharring and charring fuels. By addressing the time dependence of the rate of mass loss of the burning face of a charring fuel, a linear integral equation of the Volterra type is derived for the spread rate.

Combustion of liquid fuel in rectangular mini and microchannels
MATEC Web of Conferences, 2016 It is shown that flame spread rate can be high and comparable with velocities of flame propagation in the stoichiometric homogeneous gas mixture. The flame spread rate depends on velocity of oxidizer.
