<p>PROBLEM TO BE SOLVED: To provide a method for calculating a heat transfer by a piston effect at a supercritical fluid in which the heat transfer can be highly accurately and easily calculated with the use of an information processing device such as a computer while a change of physical properties values by a temperature and a pressure is taken into account. SOLUTION: The method for calculating the heat transfer of the supercritical fluid consists of a first step of inputting an analysis region, an initial condition and a criticality, a second step of obtaining physical properties values on the basis of an initial temperature and an initial pressure, a third step of calculating a temperature T with the use of physical properties values obtained in the second step, a fourth step of calculating a pressure p with the use of physical properties values obtained in the second or a sixth step, a fifth step of calculating a heating value Q with the use of physical properties values obtained in the second or the sixth step, and a seventh step of calculating the temperature T with the piston effect taken into account with the use of the heating value Q and physical properties values obtained in the sixth step.</p> |
