Carbon black production from various sources by thermal cracking method

Summary:
Petroleum-based feedstock (PBFS) and Coal tar-based feedstock (CTBFS) were used for the synthesis of carbon black (CB) via thermal cracking method named as Petroleum-based feedstock carbon black (PBFS-CB) and Coal tar-based feedstock carbon black (CTBFS-CB) in a furnace reactor at a temperature of 1800 °C, for utilizing industrial waste products. The obtained distinguish carbon black samples are characterized for determining functional groups, morphology, and surface area using advanced instruments. Further, investigated physical and mechanical properties of obtained different CB samples mixed into the natural rubber. The small clusters morphology is observed in CBs. There are slight changes in spectra peaks and there no significant new peaks are observed. The same minerals observed at same theta values in XRD pattern corresponding to PBFS-CB and CTBFS-CB. The tensile strength, modulus 300% and abrasion loss of samples into rubber were determined as per international ASTM standards. The results revealed that, there are negotiable values observed in both samples due to minimal changes observed in surface area of the CB samples. These samples can be used for various applications viz rubber reinforcement, conductivity agent, colouring agent, and ultraviolet screening agent etc.

Testing of ethylene glycol ketal, dioxane and cyclopentanone as components of B10, B20 fuel blends

Summary:
The aim of the present work was to the preparation of biodiesel from sunflower oil and methanol by the transesterification reaction in the presence of the KOH. The conversion was 95% using a 1:3 molar ratio of oil to alcohol at 65°C. Important fuel physical properties of B10 and B20 fuel blends with (or without) oxygenated additivities by the ASTM standards had been investigated. Based on the obtained results is noted that the fuel blend B10 and B20 with oxygenated additivities has greater potential for diesel engines than, B100 and fossil diesel. The best result was demonstrated B10+1.4-dioxane fuel blend among the studied fuels.

INVESTIGATION OF THE PERFORMANCE CHANGES OF THE SAVONIUS WIND TURBINE ROTORS WITH THE SAME FRONT VIEW AREA OF LOOK BY CHANGE OF THE ASPECT RATIO

Summary:
In this study, Savonius type wind turbine rotors with the same front view area were produced with 3D printers by changing their aspect ratios, and then both experimental and numerical analyzes were carried out according to them attaching end plate and without end plate situations. The wind tunnel in the university was used in the experimental analysis. For numerical analysis, rotors and wind tunnels modeled in SolidWorks CAD program were analyzed in Ansys Fluent program. The analyzes made are for imaging purposes only, and the results in the experimental analyzes are accepted as correct. The reduction of aspect ratios in the uncapped analyzes decreased the overall efficiency, but the opposite effect was observed when the analyzes were repeated with the end plate. In addition, while negative pressure was observed in the rotors made without cover (bare case) in the digital images, this situation was not seen in the analyzes made with the end plate.

Phase change materials for energy efficiency in building components – Overview

Summary:
Energy demand in the building particularly in summer during peak hours due to outdoor climate and lack of sufficient high thermal mass construction materials. Advanced materials are required to reduce the recurring energy demand of buildings. This peak hour energy demand can be significantly reduced by using phase change materials (PCM). These PCMs may be incorporated into building components/ products in various ways. In this overview, the recent advances in the field of using different types of PCMs, parameters to be consider for building components, encapsulation of PCMs and influence of PCMs on thermal and mechanical properties of construction materials are briefly discussed. Importantly, behaviour of MPCM in building components is concisely elaborated in effective way.

HYDROELECTRIC POWER OVERVIEW IN 2021 OF TURKEY

Summary:
Hydroelectric power together with other renewables already accounts for about 50% of electricity demand, and there is much additional potential for growth. Turkey’s electric power demand has been developing steadily, averaging 8-10 % annual growth over the past 20 years. Turkey is rapidly growing in terms of both its economy and its population. In parallel, its demand for energy, particularly for electricity, is increasing fast.
Turkey’s hydraulic potential is 55,000 MW, and the share of hydraulic installed power has reached 31.647 MW from 11,175 MW in 2000 as of 31 December 2021. According to the Strategic Plan of the Ministry of Energy and Natural Resources for 2019-2023, while the total installed capacity will be about 32.9% in 2023, but this figure has already been reached.In cooperation with the public - private sector, 743 Hydroelectric Power Plants (public +private) with an installed capacity of 31.647 MW and a power generation potential of 108.932 GWh/year have been completed and put into service. Construction of those made by the public from these facilities is carried out by the DSI (State Hydraulic Works) and their operation is transferred to EUAS (Electricity Generation Corporation), while those made by the private sector, except for the EMRA license, other (water Use agreement, project, construction, water structures acceptance, etc.) operations are performed by DSI.
From 743 facilities; 68 plants with an installed power of 13.766 MW with a power generation potential of 49 GWh/year by DSI; 675 plants with an installed power of 17.881 MW and a power generation potential of 60 GWh/year were built by the private sector and put into operation.
This study aims to overview the status of hydropower in 2021 data of Turkey.
