Exergy Transfer Criteria on Enhanced Heat Transfer Performance Evaluation

Advanced Energy Systems, 2006
Based on the exergy transfer performance analysis of forced convective heat transfer through a tube with constant heat flux/ constant wall temperature for thermally and hydrodynamic fully developed turbulent flow, extended performance evaluation criteria for enhanced heat transfer surfaces based on the exergy transfer theorem have been developed.

Effect of Heat Transfer on the Performance of Thermoelectric Heat Pumps

Journal of Non-Equilibrium Thermodynamics, 2001
AbstractThe performance analysis of thermoelectric (semiconductor) heat pumps is performedusing the combined method of finite time thermodynamics and non-equilibriumthermodynamics. The heating load and coefficient of performance (COP) expressionsfor the heat pump, which is composed of multi-elements, are derived with con-siderations of heat transfer ...

High Performance Passive Solar Heating System with Heat Pipe Energy Transfer

1984
The aim of this project was to develop a passive solar heating system with a higher efficiency than concrete thermal storage walls and with restricted extra costs for manufacturing the system. This is to be achieved by three special components: 1) a heat pipe as a thermal diode tube for efficient transfer of collected solar heat from the absorber to ...

Extended performance evaluation criteria for enhanced heat transfer surfaces: heat transfer through ducts with constant heat flux

International Journal of Heat and Mass Transfer, 2001
The objective is to derive criterion equations for enhanced heat transfer surfaces based on the entropy production theorem to include the effeet of fluid temperature variation along the length of a tubular heat exchanger. The equations originate from various design constraints, and generalize the performance evaluation criteria for enhanced heat ...
