1. 1. A Comparison Between FDS and the Multi-Zone Fire Model Regarding Gas Temperature and Visibility in Enclosure Fires

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Benjamin Waldeck; [2020]
   Keywords : Enclosure fire; FDS; Multi-Zone Fire Model; gas temperature; Visibility; Technology and Engineering;

   Abstract : When designing large buildings with complex geometry there is often a need for performance-based design and the use of computer models. CFD models like FDS that are available and validated for this purpose are typically time consuming and require large amounts of computing power. READ MORE

3. 2. Numerical modelling for characterization of the granular flows impact on the gas flow in a packed-bed-reactor

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Anton Sundström; [2020]
   Keywords : DEM; Discrete element method;

   Abstract : The goal of the project was to characterize the granular flows impact on the gas flow in a packed-bed-reactor. The study was created at Swerim as a master's thesis for Luleå University of Technology. The packed-bed-reactor geometry used in this study is a scaled down blast furnace model. READ MORE

4. 3. Numerical Study on Air Demand of Free Surface Flows in a Discharge Tunnel

   University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutionen för fysik och astronomi

   Author : Jonathan Barassa; Rickard Nordlöf; [2020]
   Keywords : Computational Fluid mechanics; Hydropower; Air demand; Free surface flows; ANSYS Fluent;

   Abstract : Aeration issued through a ventilation shaft is an important measure to prevent cavitation and large gauge pressure in flood discharge tunnels. In order to dimension the ventilation shaft appropriately, itis necessary to have a good understanding of the air-water flow in the tunnel. READ MORE

5. 4. Conceptual design and construction of a UAV wing structure

   University essay from KTH/Skolan för teknikvetenskap (SCI); KTH/Skolan för teknikvetenskap (SCI)

   Author : Selma Rahman; Anujan Ranganathan; [2020]
   Keywords : ;

   Abstract : This report presents the design of the wing structure for a UAV called Skywalker X8. A model of the UAV was given and analyzed to design a wing box structure that is twice the size of the current model, with "greener" technology and lightweight materials. READ MORE

6. 5. Approaches for improving the rheological characterization of fermented dairy products

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

   Author : Abdulrahman Muhammad; [2020]
   Keywords : food engineering; livsmedelsteknik; Technology and Engineering;

   Abstract : Fermented dairy products are wildly consumable products in today societies, and these products are known for their unique rheological properties due to the complex structural systems they possess. The simplest rheological model for describing yogurt behavior is the Power Law model, but this model parameters are not sufficient for describing the complex behavior during flow and filling.
