The paper introduces the results of the validation of two contemporary CFD techniques for numerical analysis of transient combustion phenomena. Dissipation-free numerical technique (CABARET) and pseudo spectral method are outlined and validated by using several benchmarks. Three basic test routines are suggested among which are: one-dimensional steady flame, one-dimensional and two-dimensional unsteady flames. It is shown that both analyzed numerical techniques possess a set of advantages including extremely low values of scheme dissipation and dispersion. This allows reproducing the evolution of non-steady multidimensional flows with high accuracy. The disadvantages of conventional finite-difference schemes and the limits of their applicability are discussed. A full description of the proposed test routines is provided; one can utilize them to carry out validation of the reactive CFD codes.
