A review of phase change material and performance enhancement method for latent heat storage system
Y.B. Tao,Ya-Ling He +1 more
TL;DR: In this article, a comparative review of phase change material (PCM) based LHS performance enhancement methods is presented, which can be classified into three categories: using high thermal conductivity additives and porous media to enhance PCM thermal conductivities, using finned tubes and encapsulated PCMs to extend heat transfer surface, using multistage or cascaded LHS technique and thermodynamic optimization to improve the heat transfer uniformity.

Effectiveness–thermal resistance method for heat exchanger design and analysis
TL;DR: In this paper, the authors defined the equivalent thermal resistance of a heat exchanger, which measures the irreversibility of heat transfer for the purpose of object heating or cooling, rather than from the heat to work conversion.

Progress in study on constructal theory and its applications
TL;DR: The emergence and development of constructal theory, which has been a new discipline branch to research sorts of structures in nature and engineering, are reviewed in this paper, where various shapes and structures of the matters in nature are generated from the tendency to obtain optimal performance.

Reciprocal Relations in Irreversible Processes. II.
TL;DR: In this article, a general reciprocal relation applicable to transport processes such as the conduction of heat and electricity, and diffusion, is derived from the assumption of microscopic reversibility, and certain average products of fluctuations are considered.

Fluctuations and Irreversible Processes
Lars Onsager,S. Machlup +1 more
TL;DR: In this paper, the probability of a given succession of (nonequilibrium) states of a spontaneously fluctuating thermodynamic system is calculated, on the assumption that the macroscopic variables defining a state are Gaussian random variables whose average behavior is given by the laws governing irreversible processes.
