Guide and control of thermal conduction with isotropic thermodynamic parameters based on a rotary-concentrating device

Abstract

In this paper, a rotary-concentrating device for thermal conduction is constructed to control and guide thermal energy transmitting in elastic plates. The designed device has the ability of concentrating for thermal conduction and controlling the processes of thermal diffusion in a plate. The multilayered isotropic material properties of the rotary-concentrating device are derived based on the transformation and rotary medium method and a rotation parameter to control the thermal diffusion process is introduced. The efficiency of the rotary-concentrating device for thermal conduction is verified. Stability of temperature fields in a plate with the rotary-concentrating device is analyzed to study the performance of rotary-concentrating. Numerical examples show that the constructed rotary-concentrating device for thermal conduction can effective rotate and focus on the thermal energy into the device for a wide range of diffusion temperatures, which can enhance the thermal conduction. Therefore, this study can provide a theoretical support for potential applications in fields of energy harvesting and thermal conduction control.
