There are provided a method and device for analyzing fluid around a rotating body that will make it possible to calculate an average over time of a physical quantity pertaining to a fluid. The method includes: a step (S100) in which a spatial model having a rotating computational mesh cell group (A) which represents a space between the rotating body (2) and an imaginary boundary (L) that covers the rotating body (2), and a stationary computational mesh cell group (B) which represents a space to an exterior of the imaginary boundary (L), is acquired; a step (S101) in which a storage computational mesh cell group (C) is established in the space between the rotating body (2) and the imaginary boundary (L); a step (S102) in which arithmetic operations for fluid analysis are performed in which the arithmetic operations are carried out with respect to a physical quantity pertaining to the fluid for each computational mesh cell as a location of the stationary computational mesh cell group (B) is held in place and the rotating computational mesh cell group (A) is made torotate about a rotational axis (2C); a step (S103) in which the physical quantity at the computational mesh cell making up the rotating computational mesh cell group (A) calculated as a result of the arithmetic operations for fluid analysis is copied to a corresponding computational mesh cell at the storage computational mesh cell group (C); and a step (S104) in which averages over time are calculated for the physical quantities at the storage computational mesh cell group (C) and the stationary computational mesh cell group (B).
