Hydrogen/air laminar flame propagating between two parallel plates was modeled with 3D numerical scheme based on reactive Navier Stokes equations with 9 species 21 reactions kinetics. The intrinsic flame surface instabilities were investigated under the condition with heat and momentum loss from the combustion system, which ensembles the situations inside a small scale combustion chamber. The velocity fixed non-slip wall were used for momentum conditions, while two different types of thermal conditions were applied, i.e., adiabatic and isothermal wall to study the effect of heat loss. Dispersion relations were obtained for both conditions with different channel heights. It was found that the reducing the channel height increases the flame surface instability both with and without the heat loss.
