Establishment and evaluation of a co-effect structure with thermal concentration–rotation function in transient regime
Transient temperature profiles of three structures at different times: (a) single concentrator, (b) single rotator, (c) co-effect structure, the black arrows represent heat flux. The dimension of the whole simulation domain is 0.8 cm × 0.8 cm, both upper and lower boundaries are thermally isolated, left and right boundaries are respectively fixed at temperature T = 400 K and T = 100 K, leading to an applied temperature gradient of 375 K/cm. The medium of background area outside the function region is set with θ0 = 0.16 W/(m⋅K) and ρc = 1.358 × 10−3 MJ/(m3⋅K) and thermal conductivity of the transformed domain are arranged as theoretical work. The geometric parameters of annuls region are set as R1 = 0.15 cm, R2 = 0.23 cm, and R3 = 0.25 cm.
