摘要

PPROBLEM TO BE SOLVED: To provide a temperature estimation method for a fluid system capable of estimating the temperature of the entire fluid without imposing a restriction on the disposition of a temperature measurement device, even in a fluid system having a complicated flow field. PSOLUTION: The temperature estimation method for the fluid system which supplies heat and/or discharges heat includes a temperature measurement step (step S201) in which, at two or more optional actual temperature measurement points set in the fluid system, the fluid temperature is measured by a temperature measuring means disposed at the actual temperature measurement points, and an estimation step (steps S202-S204) in which, at an optional 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.
