Title:
METHOD AND DEVICE FOR ANALYZING FLUID AROUND ROTATING BODY
Document Type and Number:
WIPO Patent Application WO/2018/235490
Kind Code:
A1
Abstract:
Provided is a method for analyzing a fluid around a rotating body, with which it is possible to calculate a time average value of a physical quantity of the fluid. The method includes: a step (S100) of acquiring a space model including a rotating calculation grid group A representing a space between a virtual boundary surface L and a rotating body 2, and a stationary calculation grid group B representing a space further to the outside than the virtual boundary surface L; a step (S101) of setting a storage calculation grid group C in a space between the rotating body 2 and the virtual boundary surface L; a step (S102) of fixing the position of the stationary calculation grid group B, and executing a fluid analysis computation to compute a physical quantity of the fluid for each calculation grid while causing the rotating calculation grid group A to rotate about an axis of rotation 2C; a step (S103) of copying the physical quantity of the calculation grids forming the rotating calculation grid group A, calculated by the fluid analysis computation, to corresponding calculation grids in the storage calculation grid group C; and a step (S104) of calculating a time average value of the physical quantity in the storage calculation grid group C and the stationary calculation grid group B.
