So many results that aren't mine?
References in many bibliographies are sometimes referred to as "Surname, I", so the citations of academics whose Surname and initials are the same may occasionally interfere. This problem is often the case with citation indexes all over the world.
How can I see only citations to my article?
After searching the name of your article, you can see the references to the article you selected as soon as you click on the details section.

Abstract:

Dünya’da küresel ısınmaya neden olan sera gazı emisyonlarının temel kaynağı fosil enerji kaynaklarının yoğun olarak kullanılmasıdır. Fosil enerji kaynaklarının alternatifi yenilenebilir enerji kaynaklarıdır. Güneş enerjisi, yenilenebilir ve yakıt kullanmayan özelliğiyle en temiz enerji kaynağı olarak kabul edilmektedir. Güneş enerjisi elektrik ve ısıl dönüşümler yoluyla kullanılmaktadır. Güneş enerjisinden ısıl enerji dönüşümünde güneş kollektörleri kullanılmaktadır. Güneş kollektörleri hava ve su ısıtma amacıyla tasarlanmış sistemlerdir. Bu çalışmada Isparta koşullarında güneş kollektörlerinde, farklı tasarım ve malzeme kullanımının üretilecek enerji ve kollektör verimi üzerine etkilerinin belirlenmesi hedeflenmiştir. Kollektörlerde malzeme olarak farklı yutucu yüzey ve izolasyon maddeleri öngörülmüştür. Hesaplamalarda, 7 yutucu yüzey ve 5 yalıtım malzemesi kullanımına göre simülasyonlar yapılmıştır. Tasarım parametresi olarak yalıtım malzemesi kalınlığı ve boru sayısı kullanılmıştır. Çalışmada 4 farklı boru sayısı ve 4 farklı yalıtım malzemesi kalınlığı için simülasyonlar gerçekleştirilmiştir. Çalışma sonucunda Isparta koşulları için en uygun eğim açısının 28° olduğu tespit edilmiştir. Yalıtım ve yüzey malzemesi kullanımıyla kollektörlerin yıllık veriminin %30’dan %44’e yükselebileceği ve tasarım parametreleriyle bu verimin %47 seviyelerine taşınabileceği ortaya konulmuştur.

Identification of the Effects of Different Design and Use of Materials on Energy and Efficiency in the Isparted Conditions of Flat Water Heating Solar Collectors
2020
Author:  
Abstract:

The main source of greenhouse gas emissions that cause global warming in the world is the intense use of fossil energy sources. The alternative to fossil energy sources are renewable energy sources. Solar energy is considered to be the cleanest source of energy with its renewable and non-fuel properties. Solar energy is used through electricity and thermal conversions. Solar collectors are used to convert thermal energy from solar energy. Solar collectors are systems designed for air and water heating. This study aims to determine the effects of the different design and use of materials in the solar collectors in the Isparta conditions on the energy and collector efficiency that will be produced. In the collectors, different sulphur surfaces and insulation materials are provided as material. In calculations, simulations were made according to the use of 7 sulphur surfaces and 5 insulation materials. The design parameter is the thickness of the insulation material and the number of pipes. The study performed simulations for 4 different tubes and 4 different insulation materials thickness. The study finds that the most suitable curve angle for the Isparta conditions is 28°. It has been found that with the use of insulation and surface materials the annual yield of collectors can rise from 30% to 44%, and the design parameters can move this yield to 47% levels.

Abstract:

The main source of greenhouse gas emissions that cause global warming in the world is the intense use of fossil energy resources. Alternative to fossil energy sources are renewable energy sources. Solar energy is regarded as the cleanest energy source as a renewable and fuel-free resource. Solar energy; it is used through electrical and thermal transformations. Solar collectors are used in thermal energy conversion from solar energy. Solar collectors are used for air and water heating. In this study, it is aimed to determine the effects of using different designs and materials on solar collectors used in Isparta conditions on the energy and collector efficiency to be produced. Different absorbing surface and isolation materials have been foreseen as materials in the collectors. In the calculations, the use of 7 absorptive surfaces and 5 insulation materials has been predicted. Insulation material thickness and pipe number are used as design parameters. In the study, simulations were carried out for 4 different pipe numbers and insulation material thickness. In the results of study; it was determined that the most suitable angle of inclination for Isparta conditions was 28 °. It has been demonstrated that the annual efficiency of collectors can increase from 30% to 44% with the use of insulation and surface material, and this efficiency can be increased to 47% with design parameters.
