Miscible density driven convective mass transfer process analysis based on Entransy dissipation theory [PDF]

open access: yes, 2014
Density driven convective mass transfer process in porous media is one of the most universal phenomena in underground aquifer. In this study, an original model defining Nu (or Sh) number for miscible mass transfer system was derived, based on basic ...

On the enhancement of heat transfer in a backward-facing step using porous baffles [PDF]

open access: yes, 2023
The backward-facing step is a geometry often used not only to investigate the accuracy and performance of numerical models, but also to analyse fundamental flow and heat transfer characteristics, and the impact of different configurations for the most ...

The Application of Entransy Dissipation Theory on the Performance Analysis of an Irreversible Atkinson Cycle [PDF]

open access: yesUniversal Journal of Mechanical Engineering, 2013
Several techniques on the Second Law of Thermodynamics have been used in the past for the analysis of Air standard Cycles. The terms used for these techniques include irreversibility analysis, entropy generation minimization, exergy analysis and thermodynamic efficiency.

Optimum insulation thickness determination using the environmental and life cycle cost analyses based entransy approach [PDF]

open access: yes, 2015
In this study, optimum insulation thickness is investigated according to the entransy loss. Analyses are carried out using rockwool and glasswool as insulation materials. Two different analyses are applied to the building walls.

Review of Shape and Topology Optimization for Design of Air-to-Refrigerant Heat Exchangers [PDF]

open access: yes, 2018
Air-to-refrigerant heat exchangers (HXs) have been the topic of exhaustive research as they are fundamental components of HVAC&R systems. It has been well-established that the large airside thermal resistance dominates the HX thermal resistance, and thus

Study on Thermal Performance of Gas Cooler for CO2 Heat Pump Water Heater

open access: yesZhileng xuebao, 2019
The heat transfer process in a gas cooler can be divided into three parts, namely pre-, quasi-, and post-critical temperature intervals, which are based on the carbon dioxide (CO2) critical temperature at a maximum constant pressure specific heat ...
