RELATIONSHIP INFORMATION SETTING METHOD, FLOW VELOCITY DETERMINATION METHOD, RELATIONSHIP INFORMATION SETTING SYSTEM, AND FLOW VELOCITY DETERMINATION SYSTEM AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/142456
Kind Code:
A1
Abstract:
The relationship information setting method according to one embodiment determines relationship information that indicates the relationship between the flow velocity of a fluid flowing inside a pipe and the temperature distribution of the surface of the pipe, wherein said method comprises: a heat exchange step in which heat is exchanged at a prescribed portion of the surface of the pipe; a temperature boundary coefficient acquisition step in which a value is acquired for a temperature boundary coefficient that takes on a resulting value obtained by dividing a constant value by the Prandtl number, the temperature boundary coefficient indicating a quantitative ratio of the fluid contributing to the transmission of heat by heat exchange performed at the prescribed portion of the surface of the pipe, from amongst the fluid flowing in the pipe; and a relationship information setting step for determining the relationship information on the basis of the value of the temperature boundary coefficient acquired in the temperature boundary coefficient acquisition step.
