Two-dimensional (2D) and quasi-two-dimensional (quasi-2D) simulations of lean premixed hydrogen-air flames have been performed using a reduced one-step kinetics and simple transport model to analyze how the resulting losses of momentum and heat affect the characteristic flame propagation patterns under confinement.
