Application of the lambda-scheme to a chemically reacting supersonic jet flow

The lambda-scheme is used as the basic integration method to compute the inviscid, chemically reacting flow of a supersonic jet. To encounter the different time scales characteristic of the fluid and chemical processes, during the explicit integration of the time-dependent problem equations, the chemical source terms for species and energy are replaced by averaged integral values. With the definition of the averaged source terms, special regard is given to the physical fact that chemical reactions occur simultaneously with the transport of the species along particle paths.
