In the first place, the thermal properties of carbon dioxide near its liquid-vapor critical point are discussed. It is calculated that the heat capacity ratio and isobaric expansion coefficient of supercritical fluids are extremely high. Furthermore, the simulation for piston effect in supercritical carbon dioxide between two infinite vertical walls is presented. The numerical results prove that piston effect has a much faster speed of heat transfer than thermal conduction under microgravity conditions. Moreover, the piston effect turns out to be stronger when closer to the critical point.
