- Abstract
A meta-material thermal concentrator model was simulated with different operating modes and different constructions based on sensu-shaped unit. The temperature and entropy generation rate was obtained by transient calculation. Thermal concentration ratio was defined with temperature and entropy production rate, which was used to analyze and evaluate performance. Thermal concentration ratio had the biggest value and thermal concentrator had the best effect at initial stage of the process. A larger temperature difference or smaller center distance leaded to better thermal control effect.
