PROBLEM TO BE SOLVED: To provide a fluid analysis method reducing calculation cost and considering the behavior of air bubbles easy for calculation and setting, a fluid analysis program and a recording medium. ! SOLUTION: A fluid analysis method includes the steps of: creating a model geometry of a process with gas-liquid two-phase flow; creating many minute elements; setting a boundary condition; setting a calculation condition; executing calculation with a computer; and in analysis of single phase flow having only a liquid phase using a momentum conservation formula, making the sum of gravity, buoyancy and resistance per a unit volume applied to the air bubbles as virtual volume force into a source term of the momentum conservation formula. !
