Entransy analysis of open thermodynamic systems

LK-INTERIOR SYSTEMS AS SYSTEMS OF “ALMOST OPEN” L-SETS

We study interior operators and interior structures in a fuzzy setting.We investigate systems of “almost open” fuzzy sets and the relationshipsto fuzzy interior operators and fuzzy interior systems.

Thermodynamic analysis of three combined power and refrigeration ‎Systems based on a demand

Three combined power and refrigeration system are introduced to compare and analyze for a defined demand and same fuel consumption based on thermodynamic parameters in a 24 hours period. Gas turbine and/or steam turbine are used for power generation and also ejector refrigeration cycle is used to produce cooling. These three systems are named as GER, SER and GSER. The results of three systems a...

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

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 that based on entropy generation minimizat...
