<p><P>PROBLEM TO BE SOLVED: To provide a technology for calculating the motions of each fluid and the interface of the fluid with high precision and high speed without generating any numerical vibration on the interface, concerning the low speed flow of a compressive and two-phase flow including an interface. <P>SOLUTION: A numerical calculation device includes: an acquisition means for acquiring data including the initial conditions of two fluid; a calculation means for performing the numerical calculation of the motion of the two fluid by solving a governing equation concerning a dispersed space and time by using the data; and an output means for outputting the calculation result of the calculation means. The numerical calculation device collateralizes the continuity of the speed on the interface of the two fluid under one flow speed assumption, and limits the retrieval range of numerical solutions by a law of conservation of mass/law of energy conservation/state equation. Thus, the numerical calculation device suppresses the generation of the numerical vibration on the interface. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
