Document Type and Number:
WIPO Patent Application WO/2018/142475
Kind Code:
A1
Abstract:
The relationship information setting method according to an embodiment of the present invention is for obtaining relationship information indicating a relationship between the flow speed of a fluid flowing through the inside of a piping and a temperature distribution on the surface of the piping, wherein the relationship information setting method includes: a heat exchange step for performing heat exchange in a predetermined portion of the surface of the piping; an analysis step for obtaining an analysis value of the temperature distribution on the surface of the piping in a state in which heat exchange is being performed in the predetermined portion of the surface of the piping; a heat transfer coefficient correction coefficient value acquisition step for acquiring the value of a heat transfer coefficient correction coefficient for correcting the analysis value of the temperature distribution on the surface of the piping in a state in which heat exchange is being performed in the predetermined portion of the surface of the piping, the heat transfer coefficient correction coefficient taking a value having a single peak between a rising position and a heated-part center position in the pipe axis direction of the temperature distribution; and a relationship information setting step for correcting the analysis value acquired in the analysis step on the basis of the value of the heat transfer coefficient correction coefficient acquired in the heat transfer coefficient correction coefficient acquisition step.
