Prospects for utilisation of solar driven ejector-absorption cooling system in Turkey
(Pergamon-Elsevier Science Ltd, 2004)
Solar assisted refrigeration appears to be a promising alternative to the conventional electrical driven units. The main advantages of solar assisted refrigeration systems concern the reduction of peak loads for electricity ...
Thermodynamic analyses of refrigerant mixtures using artificial neural networks
(Elsevier Sci Ltd, 2004)
The aim of this study is to make a contribution towards the efforts of reducing the use of CFCs by finding a drop-in replacement for pure refrigerants used in domestic and industrial appliances. The suggested solution is ...
Investigation of the effect of rake angle on main cutting force
(Elsevier Sci Ltd, 2004)
This paper presents a study of comparison of empirical and experimental results for main cutting force during machining rotational parts by unworn cutting tools. A dynamometer was designed and produced for measuring the ...
Computer aided modelling of flexible forming process
(Elsevier Science Sa, 2004)
Flexible forming enables the production of sheet metal parts with complex contours and bends by utilising a flexible medium, such as natural or synthetic rubber, as one half of a conventional die set. This study is concerned ...
Performance analysis of ejector absorption heat pump using ozone safe fluid couple through artificial neural networks
(Pergamon-Elsevier Science Ltd, 2004)
Thermodynamic analysis of absorption thermal systems is too complex because the analytic functions calculating the thermodynamic properties of fluid couples involve the solution of complex differential equations and ...
Artificial neural network analysis of heat pumps using refrigerant mixtures
(Pergamon-Elsevier Science Ltd, 2004)
In this study, we have investigated the performance of a vapor compression heat pump with different ratios of R12/R22 refrigerant mixtures using artificial neural networks (ANN). Experimental studies were completed to ...
An experimental and numerical investigation of strength characteristics of carbon-epoxy pinned-joint plates
(Elsevier Sci Ltd, 2004)
An experimental and numerical study has been carried out to investigate the strength of a pinned-joint carbon epoxy composite plate with [0degrees/45degrees/-45degrees/90degrees]s and [90degrees/45degrees/-45degrees/0degrees]s ...
Performance comparison of CFCs with their substitutes using artificial neural network
(John Wiley & Sons Ltd, 2004)
In order to decrease global pollution due to chlorofluorocarbons (CFCs), the usage of HFC- and HC-based refrigerants and their mixtures are considered instead of CFCs (R12, R22, and R502). This was confirmed by an international ...
Estimation of solar potential in Turkey by artificial neural networks using meteorological and geographical data
(Pergamon-Elsevier Science Ltd, 2004)
Turkey is located at the Mediterranean at 36degrees and 42degrees N latitudes and has a typical Mediterranean climate. The solar energy potential is very high in Turkey. The yearly average solar radiation is 3.6 kW h/m(2) ...
Investigation of thermodynamic properties of refrigerant/absorbent couples using artificial neural networks
(Elsevier Science Sa, 2004)
This paper presents a new approach to determine the properties of liquid and two phase boiling and condensing of two alternative refrigerant/absorbent couples (methanol-LiBr and methanol-LiCl), which do not cause ozone ...
