The governing equations of relativistic computational fluid dynamics (CFD) are integrated numerically. The equation of state (EOS) for a gas at relativistic temperature (the thermal energy of a gas particle is on the order of its rest mass energy) is obtained as a polynomial approximation for a gas

J. 188, 489, 1974) for the Newtonian gas dynamics to peated for the next time step. The choice of the size of relativistic gas dynamics is presented. It is found that the relativistic the time step is dictacted by the Courant-Friedrich-Lewy Euler equations are split into a set of discrete conservation laws stability condition that physically no beam of gas travels with beam split conservative state vectors and flux vectors. Highfarther than one cell spacing in one time step. For further order accurate schemes using essentially nonoscillatory concept are devised. Formulations for two space dimensions are also included. details see [13]. The beam scheme, although it is a particle

Gas-kinetic schemes based on the BGK model are proposed as an alternative evolution model which can cure some of the limitations of current Riemann solvers. To analyse the schemes, simple advection equations are reconstructed and solved using the gas-kinetic BGK model. Results for gas-dynamic applic
