Modelling and performance analysis of linear fresnel collector for process heat generation for ice cream factory in Konya
Singh, Rahul; Baker, Derek Keıth; Tarı, İlker; Department of Mechanical Engineering (2017)
In this thesis, a linear Fresnel collector has been designed to supply solar heat for industrial process. Firstly, optical analysis using ray tracing is done to determine the effects of collector’s parameters, such as height of receiver, mirror width and profile, gap between adjacent rows and slope deviation. Afterwards, one-dimensional thermal model is presented which predicts surface temperatures of receiver components and heat loss. The results obtained from both optical and thermal studies are then benc...
Modeling and financial analysis of a solar-biomass hybrid power plant in Turkey
Özdemir, Merve; Yozgatlıgil, Ahmet; Department of Mechanical Engineering (2017)
Solar thermal and biomass combustion systems can be hybridized via a Rankine cycle to have a continuous electricity generation and lower CO2 footprint. Disadvantages of these two renewable technologies can be overcome by hybridization. In this work; we develop a simulation model for Rankine cycle based, solar-biomass hybrid power plants using the ASPEN PLUS software. Solar parabolic collectors and biomass combustion are arranged in parallel to produce steam for power generation. Using the simulation model; ...
Conceptual design and heat transfer investigation of a dense granular flow solar receiver
Johnson, Evan Fair; Baker, Derek Keıth; Tarı, İlker; Department of Mechanical Engineering (2017)
Solid particles have previously been proposed as an alternative to molten salt as a heat transfer and heat storage medium for concentrating solar power plants. While previous solid particle solar receiver designs use fluidized or falling particles, the new type of receiver proposed in this thesis uses a gravity-driven flow of particles in a dense granular flow regime. Through experimentation with sand, the flow and heat transfer properties were studied in two geometries: vertical tubular and vertical parall...
