PROBLEM TO BE SOLVED: To provide an analysis technology capable of more accurately handling a characteristic phenomenon on an interface of a multiphase flow.SOLUTION: An analyzer uses a renormalized molecular dynamics method to analyze a multiphase flow. The analyzer comprises: a particle system acquisition unit that acquires a particle system including multiple particles for describing the multiphase flow; a force calculation unit that calculates force working on the particles on the basis of distance between the particles; and a particle state calculation unit that calculates at least one of a position of each particle and its speed by applying the force calculated by the force calculation unit to a motion equation of discretized particles. The multiphase flow means a flow in which at least a first phase is mixed with a second phase having lower particle density than the first phase. Each first-phase particle has a particle diameter to be obtained by renormalization processing, and each second-phase particle has a particle diameter larger than the particle diameter obtained by the same renormalization processing as the renormalization processing applied to the first phase. |
