Title:
TEMPERATURE ESTIMATION METHOD AND DEVICE FOR FLUID SYSTEM, AND METHOD FOR ESTIMATING CONCENTRATION AND TEMPERATURE OF SUBSTANCE COMPONENT IN FLUID SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/096518
Kind Code:
A1
Abstract:
A temperature estimation method for a fluid system which supplies heat and/or discharges heat comprises a temperature measurement step (step S201) in which at two or more arbitrary defined actual temperature measurement points set in the fluid system, the fluid temperature is measured by temperature measurement means disposed at the actual temperature measurement points, and an estimation step (steps S202-S204) in which at an arbitrarily defined temperature estimation point set in the fluid system, an index relating to the flow field of the fluid system at the temperature estimation point is acquired, the index being found experimentally or by a numerical fluid simulation, and the temperature at the temperature estimation point is estimated on the basis of the index and the temperature measured in the temperature measurement step. Consequently, even in a fluid system having a complicated flow field, the temperature of the entire fluid can be estimated without imposing a restriction on the disposition of a temperature measurement device.
