• We apply a new way for the construction of efficient non-oscillation shock-capturing schemes, namely artificial wind (AW) scheme, for relativistic hydrodynamics (RHD) simulations in astrophysics. We also discuss physical foundations for computational RHD. An appropriate choice for a realistic equation of state of the matter at relativisitic temperatures drastically facilitates the procedure for numerical integration of hydrodynamics equations. The time-consuming iteration approach to solve the coupling equation is avoided. We have developed a 2-D relativistic hydrodynamics code based on the AW scheme and the new RHD. Here we present two applications of the code in astrophysics, namely, numerical simulations of ultra-relativisitc jet propagation and relativisitc Richtmyer-Meshkov instability.
