Second law analysis and heat transfer in a cross-flow heat exchanger with a new winglet-type vortex generator
(Elsevier Ltd, 2010)
In this paper a second law analysis of a cross-flow heat exchanger (HX) is studied in the presence of a balance between the entropy generation due to heat transfer and fluid friction. The entropy generation in a cross-flow ...
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 ...
Experimental study on the heat transfer and pressure drop of a cross-flow heat exchanger with different pin-fin arrays
(2011)
In this study, convective heat transfer and pressure drop in a cross-flow heat exchanger with hexagonal, square and circular (HSC) pin-fin arrays were studied experimentally. The pin-fins were arranged in an in-line manner. ...
Sizing problem for a cross flow heat exchanger with wing-type vortex generator
(2009)
In the present study, sizing of a single pass cross flow heat exchanger with unmixed fluid streams has been investigated. The heat exchanger is a cross flow heat exchanger. It has overall dimensions of 20 × 20 × 20 cm. Two ...
Properties and tribologic behavior of titanium carbide coatings on AISI D2 steel deposited by thermoreactive diffusion
(Minerals, Metals and Materials Society, 2018)
In the present study, the metallographic, mechanical and tribologic behaviors of AISI D2 steel specimens coated with TiC through the titanizing process were investigated. The titanizing treatment was performed at the ...
A comparative study on the effects of different thermochemical coating techniques on corrosion resistance of STKM-13A steel
(Springer Boston, 2018)
The corrosion resistances of three different thermochemical coatings (grown using titanizing, boriding, and borotitanizing treatments) applied to STKM-13A steel surfaces were investigated. The coatings were characterized ...
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 ...
Investigation of the component exergy efficiencies of a two stage vapour compression cycle
(Inderscience Enterprises Ltd., 2018)
The exergy efficiencies of the components (compressor I and II, condenser, evaporator and flash tank) of a two stage vapour compression refrigeration cycle were analysed with respect to evaporator and condenser temperatures ...
Irreversibility analysis of a compression refrigeration cycle using natural refrigerants for a sustainable future
(2012)
Irreversibility analyses of R290, R717, R718 and R744 are carried out in a compression refrigeration cycle. The effects of evaporator temperature, condenser temperature and isentropic efficiency on the irreversibility of ...
