Simulation method, simulation device, and computer readable medium storing program

A simulation device comprising:

• a simulation condition acquisition unit that acquires of physical property values of a fluid and particles of a fluidized bed to be simulated, and initial conditions of physical quantities defined for the fluid and the particles, the fluidized bed including the fluid and a plurality of the particles in the fluid;
• an enlargement ratio acquisition unit that acquires an enlargement ratio for enlarging the particles;
• and
• a calculation unit that converts the initial conditions of the physical quantities and the physical property values which are acquired by the simulation condition acquisition unit, and simulates a behavior of the fluidized bed by using the converted physical property values and physical quantities, under the conditions that dimensionless quantities relating to a flow of the fluidized bed and dimensionless quantities relating to heat transport do not change even when the particles are enlarged.

A computer readable medium storing a program that causes a computer to execute a process, the process comprising:

• a function of acquiring physical property values of a fluid and particles of a fluidized bed to be simulated and initial conditions of physical quantities defined for the fluid and the particles, the fluidized bed including the fluid and a plurality of the particles in the fluid;
• a function of acquiring an enlargement ratio for enlarging the particles;
• and
• a function of converting the acquired initial conditions of the physical quantities and physical property values, and simulating a behavior of the fluidized bed by using the converted physical property values and physical quantities, under the conditions that dimensionless quantities relating to a flow of the fluidized bed and dimensionless quantities relating to heat transport do not change even when the particles are enlarged.
