1. 1. Dynamics of a CRAFT : A simulation study on a Counter Rotating vertical Axis Floating Tilting wind turbine

   University essay from Uppsala universitet/Elektricitetslära

   Author : Benjamin Hedlund Peters; Linda Goude; [2023]
   Keywords : wind power; counter rotating; contra rotating; offshore wind; floating wind power; vertical axis wind turbine; VAWT; renewable energy;

   Abstract : In this thesis the Counter Rotating vertical Axis Floating Tilting wind turbine (CRAFT) has been explored by creating a simulation model in the program Simulink. The CRAFT prototype is a new type of wind turbine under development by World Wide Wind and Uppsala University with the aim to produce a large scale floating vertical axis wind turbine (VAWT) with two cone shaped counter rotating turbines.

3. 2. Dynamic Torque Control of Brushed DC Motors for Hardware-in-the-Loop Integration

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Eric Schyllert; [2023]
   Keywords : Technology and Engineering;

   Abstract : The main goal with the thesis was to design, construct and evaluate a system able to drive and brake a mechanical axis to simulate loads and stored rotational energy - a hardware force simulator. The force simulator was then to be integrated in a existing hardware-in-the-loop testing rig to enhance the mechanical dynamics of door simulations. READ MORE

4. 3. Requirements and Analysis of an Overload Protection Mechanism for an Electromechanical Linear Actuator

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Mats Vesterberg; [2022]
   Keywords : EMA; Electromechanical Actuator; Linear Actuator; Shock load; Protection mechanism; Elektromekaniska ställdon; Linjära ställdon; Shocklaster; Överlastskydd;

   Abstract : Cascade Drives specializes in high-performance electromechanical linear actuators (EMA). The company has developed a range of linear rack and pinion actuators based on a patented load distribution technique that allows multiple pinions to interact with a single gear rack. READ MORE

5. 4. Development of a Flow Dependent Chemical Reaction Model using CFD

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

   Author : Martin Östman; [2022]
   Keywords : CFD; Fluid mechanics; Rotating Bed Reactor; Ansys Fluent; Decolorization; CFD; Strömningsmekanik; Roterande Bäddreaktor; Ansys Fluent; Avfärgningsprocess;

   Abstract : In many technical applications chemical reactions are used. One of these is a so called decolorization, in which an ion exchange resin is used to remove a dye from water. To apply this decolorization technique a Rotating Bed Reactor, or RBR for short, can be used. It is filled with the ion exchange resin and spun inside the water. READ MORE

6. 5. PIV measurements of rotational flow in a porous medium : A masters thesis in fluid dynamics and experimental mechanics

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

   Author : Björn Skarman; [2022]
   Keywords : PIV; particle image velocimetry; velocimetry; refractive index matching; porous medium; rotational flow;

   Abstract : The purpose of this work is to test the feasibility of using particle image velocimetry(PIV) for measurements of flow through a porous medium, more specifically in this casea rotating bed reactor S3. The results from experiments preformed can then be usedto validate and improve computational fluid dynamics models. READ MORE
