Numerical methods to solve Euler equations in one-dimensional steady nozzle flow

A new numerical approach to the solution of the steady one-dimensional nozz le flow has been developed. The main advantages of the new method consist i n avoiding the discontinuity, and the consequent instability, present in th e classical approach and in the simple criterion to find the transonic poin t. The former aspect is very important for flows with chemical reactions, w here the transonic point does not coincide with the minimum of the nozzle s ection. Comparisons between the new and the classical method put in evidenc e the better performances of the new approach mainly in the solution of rea cting flows. (C) 2001 Elsevier Science B.V.
