Abstract 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 effectively 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.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
