1. 1. Numerical Modeling of Aluminum Sampling Process

   University essay from KTH/Materialvetenskap

   Author : Ming Yang; [2019]
   Keywords : Numerical modeling; Aluminum sampling; Solidification process; Inclusion distribution; Ansys Fluent.;

   Abstract : Castings of aluminum alloys are widely used in the automotive and aerospace industries since they play a significant role in improving the performance and fuel efficiency. In aluminum industries, sampling is the most common method to evaluate the inclusion levels which is a key indicator for the quality of the aluminum alloys. READ MORE

3. 2. CFD for mixing efficiency in commercial and industrial advanced air oxidation

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Johan Bergström; [2018]
   Keywords : ;

   Abstract : Ozone treatment of pollutants in air is a relatively young technology with limited literature available. To the authors knowledge no literature discussing simulations of commercial ozone treatment without UV-lamps in gas phase has been published up to this point. READ MORE

4. 3. Flow Separation Control Utilizing Plasma Actuators

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Stefan Nilsson; [2018]
   Keywords : plasma actuator; flow separation control; fluid dynamics; aerodynamics; aerospace engineering; plasma physics;

   Abstract : The goal of this thesis was to both theoretically and experimentally show the effect of a plasma actuator for flow separation control.  In the theoretical part a solver was implemented in MATLAB code, to solve the governing equations describing the plasma actuator. READ MORE

5. 4. Detection and removal of wind turbine ice : Method review and a CFD simulation test

   University essay from Högskolan i Gävle/Energisystem

   Author : Ismael Bravo Jimenez; [2018]
   Keywords : renewable energy; wind turbine; ice accretion; flow simulation; CFD; wind turbine performance; anti-icing methods; de-icing methods.;

   Abstract : Nowadays, the energy sector is facing a huge demand that needs to be covered. Wind energy is one of the most promising energy resources as it is free from pollution, clean and probably will arise as one of the main energy sources to prevent global warming from happening. Almost 10% of the global energy demand is coming from renewable resources. READ MORE

6. 5. Ray Tracing and Spectral Modelling of Excited Hydroxyl Radiation from Cryogenic Flames in Rocket Combustion Chambers

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Jaka Perovšek; [2018]
   Keywords : spectral modelling; excited hydroxyl radiation; OH* radiation; ray tracing; spectroscopy; rocket combustion chambers; rocket engines; hydrogen-oxygen combustion; combustion instabilities;

   Abstract : A visualisation procedure was developed which predicts excited hydroxyl (OH*) radiation from the Computational Fluid Dynamics (CFD) solutions of cryogenic hydrogen-oxygen rocket flames. The model of backward ray tracing through inhomogeneous media with a continuously changing refractive index was implemented. READ MORE
