review text: We show that the numerical effort for the computation of steady-state solutions of inviscid and viscous flows may be reduced by application of a local time-stepping technique. A further reduction is obtained by a rigorous adaption of the integration scheme for the chemical kinetics to the characteristics of the flow problem. The number of numerical operations may be reduced on the one hand by adaptive techniques which restrict the viscous as well as the reactive region of computation and, on the other hand, by a simplified description of the physical transport coefficients. Appropriately selected numerical examples demonstrate the efficiency of the proposed techniques.
