We study the Chapman Jouguet (CJ) model and the selfsimilar Zeldovich von Neumann Do ring (SZND) model in chemically reacting gas flows. We discover some basic relationships among ignition temperature T i , total chemical binding energy Q, and the adibatic exponent # of polytropic gas. From these re
## Abstract We present a new relaxation method for the numerical approximation of the twoβdimensional Riemann problems in gas dynamics. The novel feature of the technique proposed here is that it does not require either a Riemann solver or a characteristics decomposition. The high resolution of the
