Exergy analysis of R1234yf and R1234ze as R134a replacements in a two evaporator vapour compression refrigeration system
(Elsevier Ltd, 2015)
Exergy analysis is a useful way for determining the real thermodynamic losses and optimising environmental and economic performance in the systems such as vapour compression refrigeration systems. The present study deals ...
Comparison of superheating effect of water as a refrigerant with the other refrigerants
(2011)
The performance comparison of water as a refrigerant (R718) with some refrigerants including R717, R290, R134a, and R152a is presented for a vapor compression refrigeration cycle. A computer program simulating the vapor ...
Exergy transfer in a porous rectangular channel
(Elsevier Ltd, 2009)
Present paper is performed to investigate the heat and exergy transfer characteristics of forced convection flow through a horizontal rectangular channel where open-cell metal foams of different pore densities such as 10, ...
Forchheimer forced convection in a rectangular channel partially filled with aluminum foam
(Elsevier Inc., 2016)
In this paper, heat transfer and pressure drop were investigated by placing open-cell aluminum foam in different ratios according to the channel volume in a hydrodynamically fully developed rectangular channel. Aluminum ...
Irreversibility analysis of a two-evaporator vapour compression refrigeration system
(Inderscience Enterprises Ltd., 2015)
In this study, irreversibility analysis of a two-evaporator vapour compression refrigeration system under the influence of superheating and subcooling effects was carried out. The thermodynamic properties of the refrigerants ...
Heat transfer augmentation by swirl generators inserted into a tube with constant heat flux
(2009)
A novel conical injector type swirl generator (CITSG) is devised in this study. Performances of heat transfer and pressure drop in a pipe with the CITSG are experimentally examined for the CITSGs' angle (α) of 30°, 45° and ...
Effect of swirl generator inserted into a tube on exergy transfer: Decaying flow
(Taylor and Francis Inc., 2014)
This study experimentally investigates the effect of conical injector type swirl generator inserts on heat and exergy transfer in a uniform heat flux tube for turbulence regime. One hundred twenty watts of heat are applied ...
Effect of heating position on thermal energy storage in cavity with/without open-cell metallic foams
(Taylor and Francis Ltd., 2016)
Thermal energy storage systems inherently store heat at different heating positions. In other words, the heat storage performance changes depending on the heating positions. In this study, the effects of the heating surface ...
Exergy analysis of coil-spring turbulators inserted in the horizontal concentric tubes
(2010)
In this study, to obtain definitive information about the effects of spring-type turbulators located in the inner pipe of a concentric heat exchanger, the rates of exergy transfer Nusselt number (Nue) and exergy loss (E*) ...
