Abstract

The approximate factorization method is considered for calculating a mixed stationary transonic non-potential ideal gas flow in an axisymmetric nozzle. The system of equations is written in orthogonal coordinates connected with the solution, and by raising its order, is put into a form suitable for realizing this method. The approach is shown to be efficient by taking the examples of calculating the flow parameters in a nozzle with a contour of complex geometry, the flow with given vorticity at the nozzle input, and non-adiabatic flow. The results are shown to agree well with earlier results by considering the example of potential flows in nozzles.
