Abstract

The invention belongs to the technical field related to thermodynamics, and discloses a regulation and control method for realizing a metamaterial soaking substrate. The regulation and control method comprises the following steps: S1, setting a thermal conductivity coefficient of a homogeneous substrate and the position and size of a phantom heat source on the substrate; S2, dividing the positions of non-heat sources in the homogeneous substrate and the soaking substrate to be solved into a plurality of areas, wherein the areas are in one-to-one correspondence; constructing a coordinate transformation relation between the homogeneous substrate and the soaking substrate to be solved so as to obtain a transformation matrix between the homogeneous substrate and the soaking substrate to be solved; and S3, constructing a thermal conductivity coefficient relational expression of the conversion matrix and each region on the soaking substrate to be solved, calculating the thermal conductivity coefficient of each region on the soaking substrate to be solved, and selecting a material corresponding to each region on the soaking substrate to be solved according to the thermal conductivity coefficient, so as to realize regulation and control of thermal conduction of the soaking substrate to be solved.

Description

technical field

[0001] The invention belongs to the technical field related to thermodynamics, and more specifically, relates to a control method for realizing a uniform heat substrate of a metamaterial. Background technique

[0002] Based on their artificially designed special structures, thermal metamaterials can produce various novel thermophysical properties, which have had a huge impact on the field of heat flow management. At present, the research of thermal metamaterials in the direction of heat conduction is mainly heat flow control, that is, the quantitative and directional control of heat flow is carried out by designing the geometric structure of metamaterials. At present, most of the research is based on functions such as thermal stealth, thermal transparency, and thermal phantom. Huazhong University of Science and Technology Hu et al proposed based on heat flow control that a single internal original heat source can be disguised as multiple virtual heat source ...
