1. 1. Computational Fluid Dynamics and Modeling of a Free Surface Flow

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Mathieu Marmier; [2023]
   Keywords : CFD; Free Surface Flow; VOF; STAR-CCM ; Multiphase Simulation; Nuclear Engineering; Fluid Mechanics;

   Abstract : This project deals with the CFD modelling of a free surface flow. The aim is to develop and validate a fast and accurate numerical model for stratified two-phase flows. Volume of Fluid (VOF) multiphase model is employed. The purpose is to use the developed numerical model for the design of an element within a compact nuclear reactor. READ MORE

3. 2. Flow modeling and bank erosion downstream due to spillway discharge : Independent thesis Advanced level (professional degree) 30 ECTS credits

   University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

   Author : Alexander Lindblad; [2022]
   Keywords : Ansys Fluent; Multiphase Flow; Spillway; CFD; Volume of Fluid; Reynolds-averaged Navier-Stokes;

   Abstract : Dam spillways and downstream areas are used to guide large flows of water during for example heavy rainfall. The large flows give way to turbulent pattern sand velocities that may damage the river banks or the dam structure. Investigation of these water patterns at certain flows are therefore done to examine at risk areas. READ MORE

4. 3. Simulation strategies for improved contamination modeling of liquid dynamics on automotive surfaces

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Thisal Mandula Sugathapala; Twan Bakker; [2022]
   Keywords : Volume of Fluid; Contamination modeling; Blended Kistler model; Dynamic contact angle models; Exterior water management; Light-induced fluorescence imaging; Multiphase flows; Surface flows; Computational fluid dynamics; Sensor soiling;

   Abstract : A significant level of research is currently being carried out in the development of driver support systems as they are expected to play a key role in minimizing road vehicle accidents and creating a safe driving environment under harsh weather conditions. However, the performance of some components used by existing driver support systems like LIDAR and visual cameras are affected by extreme weather conditions such as heavy rain fall and snow.

5. 4. Fluid flow features in swirl injectors for ethanol fueled rocket : - Analysis using computational fluid dynamics

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Emil Vejlens; Dylan De Jourday; [2022]
   Keywords : Fluid Mechanics; Rocket Science; Fuel injectors; Computational Fluid Dynamics; Swirling Flows; Fuel Mixing;

   Abstract : 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. READ MORE

6. 5. Numerical simulation of a rising bubble

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Nan Huang; [2021]
   Keywords : Multiphase flows; numerical simulations; Strömningsmekanik; flerfas strömningar;

   Abstract : This thesis evaluates two variants of Volumeof fluid method, namely Piecewise Linear Interface Construction (PLIC) and Multidimensional Tangent of Hyperbola for Interface Capturing (MTHINC) used in two-fluid simulations for interface tracking.Simulations of a single rising bubble in different conditions are performed aimed to assess the accuracy of the methods, and to check their convergence with grid size.
