The aim of this study is to determine instantaneous irradiance and annual percentile sunlit time on the available rooftop floor area of Technical and Social Science Vocational School at Usak University by simulation using open source software. The building of …

In the present study, energy and exergy analyses of a solar powered absorption refrigeration system are corried out by terms of the first and second laws of thermodynamics. NH3-H2O fluid couple is used in the system. The analyses are performed with the help of…

The aim of this study is to forecast installed wind power which is a one of the renewable energy resources in Turkey for the year of 2017 based on artificial neural network method using the normalized last ten-year data. An artificial neural network has been c…

Building automation and control systems (BACs) allow plants in buildings to be controlled and managed, thus increasing the users' comfort and reducing the operation and maintenance costs. As far as the lighting services are concerned, control systems offer an …

In this study, an experimental investigation of electricity production from a thermoelectric cooler heated by solar energy heat pipe has been done. For this, a heat pipe with water as the working fluid has been manufactured. Approximately 300 ml of water stora…

In this study, the effect of still water cooling on electricity generation in a thermoelectric generator heated by solar energy heat pipe is experimentally investigated. For this purpose, a heat pipe with ethyl alcohol as the working fluid has been manufacture…

Aim of the study: It is important to be able to plan the production transmission and distribution necessary for uninterrupted electricity and to use the electricity more efficiently and to make demand forecasts. For this reason, it is aimed to estimate the ele…

Refrigeration and air-conditioning systems consume about 15% of global electricity, and 46% of energy used in household and commercial buildings belongs to heating, ventilation and air-conditioning (HVAC) systems. Vapor-compression technologies dominate the HV…

Depending on the growing industry and population, energy needs are increasing day by day. In parallel, our external dependency on energy also increases. This issue made it necessary to use of renewable energy sources as much as possible. As an extension of eff…

Evrimsel algoritma ve parçacık sürü algoritması çok uzun zamandır ayrı ayrı çeşitli karmaşık problemlerin çözümünde yaygın olarak kullanılan sezgisel algoritmalardır. Evrimsel algoritma canlıların çoğalmasını ve hayatta kalmak için en iyilerin seçilmesi tekniğ…

In this work, Intralube E with 0.38 % C press-ready mix powders were pressed with 550 MPa pressure and sintered 25 min at 1120 °C. Samples were coated electrochemically with nano diamond (ND) reinforced nickel to study the effect of nano composite coating on c…

Fins are basic structures which can be easily added to many engineering designs to improve heat transfer from hot surfaces. The addition of a fin to a particular heated surface can significantly increase the cooling at no extra cost. In some cases, standard fi…

In this article, the influence of the use of three different bricks on the building heat performance is compared for use on wall surfaces as a building construction element. At the beginning of the analysis, the thermal analysis of the building was carried out…

This study presents the investigation of thorium utilization in an ADS with Lead-Bismuth Eutectic (LBE) target. To effectively burn thorium, the ThO2 fuel rods cylindrically prepared, and cladded with SiC, are mixed with 233UO2 at volumetric ratio of 1%. These…

In this paper, a thermal insulation analysis was carried out for a building using paper waste reinforced clay brick as building material. Firstly, the analysis was made using two different normal wall bricks as building material for the sample building. Later,…
