    2. Subsonic combustion propagation: laminar and turbulent deflagrations

    2.1 Laminar deflagration

    Let's take our reactive wave model from figure 2 . When combustion is slow (low velocity D ), the fresh gases have time to expand so that the transformation is quasi-isobaric. Due to this expansion, deflagration sets the fresh gases in motion in front of the combustion front (U 1 > 0). If we close the end on the burnt gas side (U b = 0) and call V F instead of D the apparent velocity...
