   University essay from KTH/Matematik (Avd.)

   Author : Gustaf Lorentzon; [2023]
   Keywords : Computational Fluid Dynamics; Convolution Filters; Convolution Kernels; Derivatives; Extracting Extra Accuracy; Filtration; Post-processing; Smoothness-Increasing Accuracy-Conserving; Signal-processing; Visualization; Vorticity; Beräkningsbaserad Strömningsdynamik; Faltningsfilter; Faltningskärnor; Derivator; Extrahering av Extra Noggrannhet; Filtrering; Efterbehandling; Kontinuitetsökande; Noggrannhetsbevarande; Signalbehandling; Visualisering; Vorticitet;

   Abstract : The ability to generate accurate approximations of derivatives holds significant importance in numerous scientific fields, including chemistry, economics and fluid mechanics. This thesis is centred around extracting hidden information in data using Smoothness-Increasing Accuracy-Conserving (SIAC) filters. READ MORE

3. 2. Range impact of a high velocity aft-propeller on a subsonic aerodynamic body

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Jens Teodor Mattsson; [2023]
   Keywords : propeller; transsonic; fluid dynamics; cfd;

   Abstract : This master’s thesis is aimed to examine the possible range increase of a ballistically fying body equipped with a propeller working at transonic velocities. To determine whetherthe propeller will provide an improvement in range, results from simulations are compared to corresponding cases of similar bodies fying without a propeller. READ MORE

4. 3. Exterior ballistics analysis for rocket propelled KE-penetrator - A conceptual simulation study within fluid mechanics and flight mechanics

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Emil Wegberg; [2022]
   Keywords : Exterior ballistics; fluid mechanics; high-speed aerodynamics; CFD; RANS; conceptual design; Ytterballistik; strömningsmekanik; höghastighetsaerodynamik; CFD; RANS; konceptuell design;

   Abstract : This study has investigated the conceptual feasibility of a rocket propelled kinetic energy penetrator (KEP), designed for the handheld recoilless rifle Carl-Gustaf® 84 mm calibre system, from an exterior ballistics perspective. The methodology is based upon evaluating the aerodynamic properties of different conceptual design proposals through CFD-simulations and then performing trajectory analysis to assess their exterior ballistic performance.

5. 4. Extended Kalman Filter as Observer for a Hydrofoiling Watercraft : Modelling of a new hydrofoiling concept, based on the Spherical Inverted Pendulum Model

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Adam Thålin; [2022]
   Keywords : Extended Kalman Filter; Hydrofoiling; Spherical Inverted Pendulum; Sensor Fusion; Simulink; Bärplan; Extended Kalman Filter; Farkostteknik; Inverterad Pendel; Sensorfusion; Sex frihetsgrader; Simulink;

   Abstract : Hydrofoiling in general has the potential to revolutionize watercraft in the future since it allows smoother and faster transport on water with less energy consumption than traditional planning hulls. Even if the concept of hydrofoiling has been around since the last century, development in control theory and material science together with increased computing power has led to a growing interest for the technology.

6. 5. 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
