N2 - A numerical method for simulating supercritical-fluid flows across the critical point is introduced. The present numerical method is based on the preconditioning method developed by the authors and mathematical models of thermophysical properties developed by Kyushu University. The thermophysical properties such as density, viscosity, heat conductivity and the derived values are rapidly changed across the critical point. Especially the isobaric specific heat has a maximum peak value. The present method can simulate both low- and high-speed flows with the anomalous properties across the critical point accurately. As numerical examples, two different supercritical carbon-dioxide flows across the critical points are calculated and the calculated results are introduced.
