Second law analysis of different refrigerants in a two stage vapor compression cycle
(Turkish Society for Thermal Science and Technology, 2015)
In this study, the second law analysis has been made by means of the program developed using the software program EES (EES-V9.172-3D) in a two stage vapor-compression refrigeration cycle for the refrigerants such as R600 ...
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 ...
Experimental investigation of a cross-flow heat exchanger with wing-type vortex generators
(2008)
In this study, heat and fluid flow in a plate-fin heat exchanger with wing-type convergent-divergent longitudinal vortex generators (CDLVGs) were studied experimentally. A cross-flow plate-type heat exchanger was designed ...
Theoretical and experimental analysis for the impact response of glass fibre reinforced aluminium honeycomb sandwiches
(SAGE Publications Ltd, 2018)
Honeycomb sandwich structures are increasingly used in the automotive, aerospace and shipbuilding industries where fuel savings, increase in load carrying capacity, vehicle safety and decrease in gas emissions are very ...

(Elsevier Ltd, 2016)
In this study, the effect of both cylindrical grooved pin-fins (C-GPFs) and triangular grooved pin-fins (T-GPFs) into the rectangular channel on heat transfer augmentation, Nusselt number and friction factor were experimentally ...
Velocity field and turbulence effects on heat transfer characteristics from surfaces with V-shaped ribs
(2012)
The flow field of smooth surfaces and surfaces with V-shaped ribs (V-SR) was studied experimentally with a Laser-Doppler Anemometry (LDA) system. In addition, heat transfer characteristics were experimentally investigated. ...
Experimental investigation of heat transfer in a channel with new winglet-type vortex generators
(Elsevier Ltd, 2014)
Both new punched triangular vortex generators (PTVGs) and punched rectangular vortex generators (PRVGs) have been developed. Both the triangular and rectangular vortex generators were directly punched from the longitudinal ...
Experimental and numerical investigation of geometry effects on multiple impinging air jets
(Elsevier Ltd, 2014)
The effect of jet geometry on the flow and the heat transfer characteristics was investigated experimentally and numerically for elliptic and rectangular impinging jet arrays. Detailed heat transfer measurements over a ...
