Generalized thermal resistance and its application to thermal radiation based on entransy theory

International Journal of Heat and Mass Transfer, 2013
Abstract Entransy is a novel concept developed in recent years to measure the transport ability of heat in heat transfer processes. In order to analyze and optimize thermal radiation process more conveniently and intuitively, we develop the entransy-theory-based method to the field of thermal radiation problems to define the generalized thermal ...

The application of entransy theory in optimization design of Isopropanol–Acetone–Hydrogen chemical heat pump

Energy, 2012
Abstract In the present work, a multi-parameter optimization approach of Isopropanol–Acetone–Hydrogen (IAH) chemical heat pump is developed based on the entransy theory. In the optimization process, the total low-temperature heat consumed by the heat pump system generally decreases while the high-temperature heat recovered by the heat pump increases ...

Optimization design of recuperator in a chemical heat pump system based on entransy dissipation theory

Energy, 2012
Based on the entransy dissipation theory, the multi-parameter optimization design of recuperator is conducted in an Isopropanol-Acetone-Hydrogen (IAN) chemical heat pump system. The performance of the heat pump system can be improved significantly through the multi-parameter optimization, when the main operation parameters of chemical heat pump remain ...

Comparison of entropy generation minimization principle and entransy theory in optimal design of thermal systems

2018
In this study, the relationship among the concepts of entropy generation rate, entransy theory, and generalized thermal resistance to the optimal design of thermal systems is discussed. The equations of entropy and entransy rates are compared and their implications for optimization of conductive heat transfer are analyzed. The theoretical analyses show
