1. 6. CFD Analyses for Wind Load AssessmentCFD Analyses for Wind Load Assessment : Wind-induced vibrations in the Bomarsunds Bridge hangers

   University essay from KTH/Bro- och stålbyggnad

   Author : Fatiha El Azrak; [2023]
   Keywords : ;

   Abstract : The trend in recent years of building longer and slender bridge components has introduced new challenges to ensure their stability and strength. This master thesis focuses on the effects of wind-induced vibrations in the context of long, slender arch bridge components, particularly the recently constructed Bomarsunds Bridge in Åland, Finland.

3. 7. Flow modeling and bank erosion downstream due to spillway discharge : Independent thesis Advanced level (professional degree) 30 ECTS credits

   University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

   Author : Alexander Lindblad; [2022]
   Keywords : Ansys Fluent; Multiphase Flow; Spillway; CFD; Volume of Fluid; Reynolds-averaged Navier-Stokes;

   Abstract : Dam spillways and downstream areas are used to guide large flows of water during for example heavy rainfall. The large flows give way to turbulent pattern sand velocities that may damage the river banks or the dam structure. Investigation of these water patterns at certain flows are therefore done to examine at risk areas. READ MORE

4. 8. Optimization and Additive Manufacturing for HPGP Rocket Engines

   University essay from KTH/Kraft- och värmeteknologi

   Author : Jessie Stachowicz; [2022]
   Keywords : Additive Manufacturing; Rocket Propulsion; Nozzle Design; Computational Fluid Dynamics; CFD; Nasa CEA; DED; PBF; High Performance Gas Propulsion; ADNbasedPropellant; CD Nozzle; Additiv tillverkning; raketframdrivningssytem; munstycksdesign; beräkningsflödesanalys; CFD; Nasa CEA; DED; PBF; högpresterande gasframdrivning; ADNbasedPropellant; Konvergerande-divergerande munstycken;

   Abstract : This thesis aims to investigate whether additive manufacturing is applicable in manufacturing the 1N thruster option that Bradford Ecaps offers. Therefore, the nozzle design is of particular interest as AM provides accessibilities to manufacturing complex structures. READ MORE

5. 9. Air Recirculation System for Electrolyte Filling Room : A CFD study of VOCs Distribution in Clean & Dry room

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

   Author : Lin Chen; [2022]
   Keywords : Clean Dry room; Air Recirculation; Air Recovery; ANSYS FLUENT; Energy-saving; Environmental impact; Building Automation system; Rent torrt rum; luftåtercirkulation; luftåtervinning; ANSYS FLUENT; energibesparande; miljöpåverkan; byggnadsautomationssystem;

   Abstract : Energy storage development is an important step for the energy transition, meanwhile Lithium-ion battery is the most common core component of electric vehicles. Over the past decade, investment has been poured into lithium-ion battery production, as a result, the production environment (Clean & Dry room) used for some processes such as Stacking, Electrolyte filling and so on and the energy consumption to maintain this special environment which precise control of air humidity and air cleanliness have become major concerns.

6. 10. Aerodynamic Analysis of a Blended Wing Body UAV

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Oliver Harrisson; [2022]
   Keywords : Computational Fluid Dynamics CFD ; Blended Wing Body BWB ; ANSYS Fluent; Aeronautics; Unmanned Aerial Vehicle UAV ;

   Abstract : The focus of this thesis is to analyse the flight characteristics of the blended wingbody (BWB) unmanned aerial vehicle (UAV) Green Raven currently being developed by students at the Royal Institute of Technology (KTH) in Stockholm,Sweden. The purpose of evaluating a BWB aircraft is due to its potential increasein fuel efficiency and payload compared to conventional aircrafts which would enable more sustainable flights. READ MORE
