1. Computational Analysis of Spray Deflector Designs
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : Planing hull is a common hull design concept which decreases the resistance while speed is increasing for a specific speed range. It is also suitable for hull modifications to achieve higher efficiency. Spray deflector is a promising hull modification which offers extra resistance decreasing and less vertical acceleration for planing hulls. LÄS MER
2. Design of compact automotive heat exchanger, analysing the effects of RANS models and utilising Additive Manufacturing
Kandidat-uppsats, KTH/FysikSammanfattning : The analytical modelling of complex turbulent airflow remains one of the great unsolved mysteries of physics, but in this paper two widely used Reynolds Averaged Navier-Stokes models (k-$\epsilon$ and k-$\omega$ SST) are compared while designing a heat exchanger for the KTH Formula Student electric race car. CAD software was used to design lattices for the heat exchanger core and theorise about how to increase heat transfer while also taking into account the utilisation of metal additive manufacturing.

3. Fluid flow features in swirl injectors for ethanol fueled rocket : - Analysis using computational fluid dynamics
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : A swirl injector for a rocket engine being developed by \emph{AESIR} (Association of EngineeringStudents in Rocketry) was simulated with different geometric parameters. The swirl injector is usedto atomize the ethanol used as fuel and to create a spray that mixes well with the oxidizer withinthe combustion chamber. LÄS MER
4. Development and validation of an improved wall-function boundary condition for computational aerodynamics
Master-uppsats, KTH/Strömningsmekanik och Teknisk AkustikSammanfattning : Computational Fluid Dynamics is a powerful and widely used tool for developing projectsthat concern flow motion, in very different fields. Industrial CFD solvers are continuouslydeveloped with the aim of improving accuracy and reducing the computational cost of thesimulations. LÄS MER
5. Energy-efficient Industrial processes : An investigation in the power consumption, power number, thrust force and torque requirement on a rotating bed reactor
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronikSammanfattning : Rotating bed reactors are used throughout the process industry. They are usedboth in the chemical industry and other industrial sectors, such as pharmaceuticals and the textile industry in decolorization due to by-products or contaminants.SpinChem AB manufactures rotary bed reactors (RBRs) to perform chemical reactions between liquids and solids.
