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 ...
Theoretical and experimental investigation of wear in internal gears
(2014)
Internal gears are commonly used in automotive and aeronautic industries as external sun gears of planetary mechanisms. Internal gears have some advantages such as low sliding velocities, low contact stresses, high contact ...
Tensile behavior of heat welded CNT network structures
(Elsevier, 2014)
In this study, a computational investigation on the mechanical properties of random carbon nanotube (CNT) networks is reported. For this purpose, atomistic models of 3-D CNT network structures are generated by an automated ...
Predicting microstructure evolution during directed energy deposition additive manufacturing of Ti-6Al-4V
(American Society of Mechanical Engineers (ASME), 2018)
Laser engineering net shaping (LENS) is one of the representative processes of directed energy deposition (DED) in which a moving heat source having high-intensity melts and fuses metal powders together to print parts. The ...
Experimental investigation of impinging jet array heat transfer from a surface with V-shaped and convergent-divergent ribs
(2012)
Detailed heat transfer measurements over a surface with V-shaped ribs (V-SR) and convergent-divergent shaped ribs (CD-SR) by a circular impinging jet array was investigated using thermal infrared camera. Both V-SR and CD-SR ...
Numerical investigation of heat transfer using impinging jets on triangular and square ribbed roughened walls
(Turkish Society for Thermal Science and Technology, 2017)
This paper presents a heat removal study on triangular and square ribbed surfaces under an array of impinging air jets. The investigation was carried out using nozzles with a 7x3 rectangular array of circular jets. The ...
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 ...
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 ...
