1. 1. Numerical and experimental investigation of multiple gas jet flow behaviour in the gas atomization process

   University essay from KTH/Materialvetenskap

   Author : Mahsa Darvishghanbar; [2022]
   Keywords : ;

   Abstract : In several industrial applications, the interaction of supersonic gas jets is encountered such as gas atomization, jet engines and the basic oxygen furnace process. In the gas atomization process, high pressure gases are converted to high velocity gas jets through convergent-divergent nozzles. READ MORE

3. 2. CFD investigation of Plate Channels

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Anton Johannesson; [2022]
   Keywords : Plate Heat Exchanger; Turbulence modelling; Generalized k-omega; GEKO; CFD; Computational Fluid Dynamics; Technology and Engineering;

   Abstract : Alfa Laval has a wide product range for plate heat exchangers that can be applied in most industries. The constant development of new and old heat exchangers drive the need for new and efficient methods that can reliably be used in the development process. READ MORE

4. 3. Implementing spatial variance in the rate of photolytic breakdown of NO2 in urban street canyons

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Fabian Friberg; [2022]
   Keywords : cfd; computational fluid dynamics; NOx; street canyon; NO2; NO; O3; photolysis; OpenFOAM; Physics and Astronomy;

   Abstract : In this study a module for calculating the solar exposure of individual fluid cells was developed to more accurately represent the effect of photolysis on the pollutant dispersion in an urban street canyon. The module was tested and validated on 12 different cases, each with a different geographical location, time of year and/or time of day. READ MORE

5. 4. Inverse Atmospheric Dispersion Modeling in Complex Geometries

   University essay from Umeå universitet/Institutionen för fysik

   Author : Charlie Pelland; [2022]
   Keywords : atmospheric dispersion modeling; dispersion modeling; invers dispersion modeling; atmospheric dispersion; invers atmospheric dispersion; CFD; computational fluid dynamics; radioactive release; openfoam; CRBN; dry deposition; dry deposition velocity; scavenging effect; wet deposition; optimization model; Reynolds Averaged Navier-Stokes; adjoint mode; time-dependent rain simulation; time-dependent rain; time dependent rain simulation; time dependent rain;

   Abstract : In the event of a radioactive release in an urban environment the consequent response mustbe swift and precise. As soon as first responders have correct information, they can make anaccurate risk assessment. However, if the position, release rate and time of the radioactiverelease is unknown it is hard to know how the pollutant will spread. READ MORE

6. 5. Verification of the fluid dynamics modules of the multiphysics simulation framework MOOSE : A work to test a candidate software for molten salt reactor analysis

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Erik Gustafsson; [2022]
   Keywords : molten salt reactor MSR ; small modular reactor SMR ; computational fluid dynamics CFD ; multiphysics; MOOSE;

   Abstract : This is a report of a verification study of the multiphysics simulation framework MOOSE which was preformed at the company Seaborg Technologies. In the process of designing molten salt reactors there is a special need of making credible multiphysics simulations since the fuel is in motion. READ MORE
