The governing equations required to analyse the linear (viscous) stability of low‐speed reacting flows are derived and a solution method based on initial value problems is described. The algorithm accurately reproduces the neutral stability curve for a non‐reacting viscous shear layer, thus providing partial validation. The results for premixed and non‐premixed flames in planar shear layers are presented and discussed.
