Technical Field

The invention relates to the field of heat flow data processing, in particular to a method and a device for processing heat flow information.

Background

In the prior art, the temperature-sensitive paint thermometry method utilizing the fluorescence temperature-sensitive effect is to spray the temperature-sensitive paint on the surface of a model, and under the irradiation of exciting light, the complete distribution of the surface temperature of the model can be obtained. It has a higher spatial resolution than conventional sensor measurements. However, this method can only provide temperature information, and in order to obtain heat flow information, the temperature information must be converted into heat flow information based on a semi-infinite assumption (i.e. the heat flow is infinitely deep inside the model). Therefore, the related art uses an indirect method to obtain heat flow information, and cannot be used when the semi-infinite assumption is not satisfied (e.g., long heat transfer time and short heat transfer distance).

In view of the above problems, no effective solution has been proposed.
