2. 1. Computational study of rivulets using Volume of Fluid

   Author : Tobias Tivert; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis focuses on numerical methods of soiling and some multiphase concepts related to it.The Volume of Fluid method was tested in two different test cases and showed fairly good results.The first test case was a gravity driven rivulet on an inclined plate, where it was an inlet with a constant water velocity at the beginning of the plate.

4. 2. A Lagrangian-Eulerian simulation method for viscoelastic flows applied to adhesive joining

   Author : Simon Ingelsten; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; volume of fluid; computational fluid dynamics; immersed boundary methods; viscoelastic flow; adhesive joining;

   Abstract : Viscoelastic flows are important for many industrial processes, such as adhesive joining, polymer extrusion and additive manufacturing. Numerical simulations enable virtual evaluation and product realization, which can support the design phase and reduce the amount of costly physical testing. However, such applications are challenging to simulate. READ MORE

5. 3. Numerical study of flows related to aerated stirred tanks

   Author : Dragana Arlov; Strömningsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasma; fluiddynamik; Gaser; plasmas; fluid dynamics; Gases; Lattice Boltzmann method; Volume of Fluid; Aerated stirred tank; Large Eddy Simulation; Eulerian-Lagrangian model; Energy research; Energiforskning; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

   Abstract : The overall purpose with this work is to investigate the bubbly flow in a aerated stirred tank using numerical simulations. Aerated stirred tanks are commonly used in chemical processes for producing for example insulin and antibiotics. READ MORE

6. 4. LES stochastic modelling of cavitation with its applications in OpenFOAM

   Author : Boxiong Chen; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cavitation; Rayleigh-Plesset Model; Simulation; OpenFOAM; Volume of Fluid Method; Modeling;

   Abstract : Cavitation is a vaporisation process that commonly happens in high pressure injectornozzles nowadays. It has been shown by previous studies that cavitationhas a significant influence on the subsequent atomization process, the qualityof which would in turn heavily affect the quality of combustion.
