description	PROBLEM TO BE SOLVED: To provide a simulation device capable of performing a high-speed calculation while keeping accuracy in a gas-liquid two-phase flow simulation.SOLUTION: A simulation device, which performs a simulation of a gas-liquid two-phase flow in a flow channel, includes an operation unit for executing an operation corresponding to the simulation by using a three-dimensional Young-Laplace formula obtained supposing that in a gas-liquid boundary between a gas and a liquid in a flow channel, a pressure of one of the two fluids is p1, and a pressure of the other is p2, that curvature radiuses of two curves, which cross each other perpendicularly, in curved surface shapes of the gas-liquid boundary surface of the two fluids are R1 and R2, and that the surface tension coefficient is , while considering a surface tension at the gas-liquid boundary. The operation part executes the operation by approximating the value of the curvature radius R2 to R2=2cos /L where L represents a length of an arc of the curve corresponding to the curvature radius R2; represents a contact angle between the flow channel and the liquid.
