A new method to capture the flame front in premixed, confined, low Mach number combustion using the flame‐sheet approximation is presented. Connected marker points represent the flame front along which a singular volumetric flux source is prescribed. Thus, the jump condition for the normal velocity is fulfilled. Application to two‐dimensional combustion in a channel with periodic boundary conditions shows good agreement to linear stability analysis of the perturbed flame front.
