1. 21. Performance Evaluation of a Photovoltaic/Thermal (PVT) Collector with Numerical Modelling

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Mila Ebrahim; [2021]
   Keywords : Solar energy; Renewable energy; Photovoltaic thermal collector; PV Thermal; PVT Collector; Performance; Numerical modelling; COMSOL Multiphysics; Ground Source Heat Pump; Solenergi; Förnybar energi; kominerad solcell solfångare; PVT panel; Prestanda; Numerisk modellering; COMSOL Multiphysics; Bergvärme;

   Abstract : In Photovoltaic/Thermal (PVT) technology, both PV and solar thermal technology are integrated in the same module for simultaneous electricity and heat production. Research has shown that there are multiple benefits from integrating PVT collectors with a ground source heat pump (GSHP) system, since it allows for seasonal storage of thermal energy over the year.

3. 22. Modelling and Simulation of Hydrogen Diffusion in High Strength Steel

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Vikas Vineeth Seru; Venkata Ramana Murthy Polinati; [2021]
   Keywords : Coupled temperature displacement; finite element software; high strength steel; hydrogen diffusion; material properties.;

   Abstract : This research is about modelling and simulation of how the hydrogen diffuses in high strength steels. The hydrogen diffusion in the material was examined by using finite element software with the help of material properties and some existing data. READ MORE

4. 23. The Church of Jesus Christ of Latter-day Saints in Trollhättan Energy optimization

   University essay from Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

   Author : William Wanli; [2021]
   Keywords : Energy performance; Energy retrofits; Energy optimization; IDA-ICE; LCC analysis;

   Abstract : The world is experiencing increasing energy usage owing to environmental impacts suchas climate change, Ozone layer depletion, and global warming. Energy usage is primarily categorized into transport, industrial, residential, and service sectors, with the transportation and industrial sectors taking up a considerable chunk of the energy use; Buildings partly determine the use of energy globally.

6. 25. Determination of Mass- and Heat Transfer Coefficients for Computer Modelling of Pharmaceutical Freeze-Drying

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Linnea Gustafsson; [2021]
   Keywords : Freeze-drying; Mass- and Heat Transfer; Pharmaceutical production; Simulation; MATLAB; Pharmaceutical technology; Technology and Engineering;

   Abstract : This thesis work deals with the determination of mass- and heat transfer coefficients for pharmaceutical vial freeze-drying and the one-dimensional steady state computer modelling of primary drying. The overall heat transfer coefficient K_V for the vial/freeze-dryer system was successfully determined using a gravimetric method. READ MORE
