Abstract: The influence of ambient temperature in the range of -42 to 25$^\circ$C on the velocity of flame spread over films of liquid and solid fuels on a metal substrate in a thermally thin system is studied experimentally. It is shown that the previously proposed model for flame spread satisfactorily describes the dependence of the flame velocity on initial temperature. A strong influence of the phase transition of the fuel into the solid phase on the flame velocity was not observed. The limit of steady-state flame spread is due to the inability to provide a sufficient thickness of the evaporating film due to the Marangoni effect.

Keywords: combustion, thermally thin system, liquid fuel.
