Abstract
A numerical method for simulating condensate flows and near-critical fluids is presented. This method is based on the preconditioning method applied to the flux-splitting scheme. A preconditioned implicit flux-splitting scheme is newly derived according to the theory of characteristics. The fundamental equations are composed of the compressible Navier-Stokes equations and additional equations for condensation. The Peng-Robinson equation of state is further introduced to evaluate the super- and near-critical state. Condensate flows and flows of supercritical fluids near the critical point at very low Mach number are calculated and the calculated results are shown.
