An analyzer analyzes a multiphase flow using a renormalized molecular dynamics method. The analyzer includes a particle system acquisition unit configured to acquire a particle system including a plurality of particles describing the multiphase flow, a force calculation unit configured to calculate a force applied to a particle based on an inter-particle distance, and a particle state calculation unit configured to calculate at least one of the position and speed of the particle by applying the force calculated by the force calculation unit to an equation of motion of a discretized particle. The multiphase flow is a flow in which at least a first phase and a second phase having a particle density lower than that of the first phase, a particle of the first phase is set to have a particle size obtained by renormalization processing, and a particle of the second phase is set to have a particle size greater than a particle size obtained by the same renormalization processing as the renormalization processing applied to the first phase. |
