Flame spreading over liquid ethanol has been experimentally characterized for ethanol for subflash temperatures, in two different channels. Three different spreading regimes have been observed. A uniform region (with flame velocities close to 10 cm/s) appears for values of the initial surface liquid temperature T∞ above a critical value Tc. For values Th<T∞<Tc an oscillatory regime occurs. For very low temperatures, T∞<Th , a new uniform regime appears with slow propagation velocities (close to 1 cm/s). The critical point Tc has been described as a Hopf bifurcation, while Th resembles a homoclinic connection
