Controlling and maximizing effective thermal properties by manipulating transient behaviors during energy-system cycles

Autor: Gao, Z. J., Shih, T. M., Merlitz, H., Pagni, P. J., Chen, Z.

Transient processes generally constitute part of energy-system cycles. If skillfully manipulated, they actually are capable of assisting systems to behave beneficially to suit designers' needs. In the present study, behaviors related to both thermal

Maximal rectification ratios for bi-segment thermal rectifiers

Autor: Shih, Tien-Mo, Gao, Zhaojing, Guo, Ziquan, Liu, Guangcao, Merlitz, Holger, Pagni, Patrick J., Chen, Zhong

We study bi-segment thermal rectifiers whose forward heat fluxes are greater than reverse counterparts. Presently, a shortcoming of thermal rectifiers is that the rectification ratio, namely the forward flux divided by the reverse flux, remains too s

Report

Entropy variation rate divided by temperature always decreases

Autor: Shih, T. M., Gao, Z. J., Merlitz, H., Rondoni, L., Pagni, P. J., Chen, Z.

For an isolated assembly that comprises a system and its surrounding reservoirs, the total entropy ($S_{a}$) always monotonically increases as time elapses. This phenomenon is known as the second law of thermodynamics ($S_{a}\geq0$). Here we analytic
