Title:
TEMPERATURE ESTIMATION METHOD AND DEVICE FOR FLUID SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/043624
Kind Code:
A1
Abstract:
A temperature estimation device acquires the flow field of a fluid system. Next, the temperature estimation device sets regions (E31-E34, E, F, G) which individually include temperature actual measurement parts (A-D), a heat absorption/generation part (E), and inflow/outflow parts (F, G), respectively, within the fluid system and do not overlap each other. Then, the temperature estimation device acquires, as downstream-side force of each of the parts (A-G), the proportion of a fluid which has reached to a temperature estimation point without passing through the other regions among fluids passing through each of the regions (E31-E34, E, F, G) in accordance with an advection diffusion phenomenon produced by the flow field or generated in each of the regions (E31-E34, E, F, G) in all fluids at the temperature estimation point. On the basis of the known temperature of each of the parts (A-G), the temperature estimation device estimates the temperature at the temperature estimation point using the downstream-side force of each of the parts at the temperature estimation point.
