Title:
FLUID TRANSITION ANALYSIS DEVICE, FLUID TRANSITION ANALYSIS METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2015/029479
Kind Code:
A1
Abstract:
On the basis of the force received by an object and experimental results or numerical calculation results for the flow around the object, a flow line analysis for the flow around the object at a given point in time is carried out, and a flow line map is obtained. On the basis of the flow line map, a single word from among words defining two types of flow patterns that can be topologically assumed for a single-connection external region having a single hole is assigned, and, for as many holes as are added, a single word from among words defining five types of operations that can be topologically assumed in a case where a single hole is added to the flow pattern is assigned. As a result, a word expression indicating the flow pattern of the flow around an object is formed, and the word expression, which indicates the flow pattern at a plurality of points in time, can be associated with the force received by the object at the given point in time.
