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

Enhanced Heat Design of a Multifeature Coupled Microchannel Heat Sink Based on Entransy Theory

Chemical Engineering & Technology
ABSTRACT Multifeature (MF) design is a potential approach for the secondary design of microchannel heat sinks (MHSs). In this paper, turning microchannels with variable cross sections (TM‐VC) were designed. The effects of different coupling methods on the convective heat transfer performance were studied.
