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. Investigation of fuel and water injection in gas turbine combustion : Evaluate the methodologies available in Star CCM+ for modeling of water injection in simplified combustor using liquid and gas fuels

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Sanger Shinwari; [2023]
   Keywords : Diesel and Methane fuel combustion; FGM combustion model; Lagrangian multiphase modelling; Inert Stream; Water injection; STAR CCM ;

   Abstract : The negative impact of gas turbine emissions on the environment and human health is a growing concern. Recent studies suggest injecting water into the combustion process effectively reduces emissions and increases power output. However, this approach presents new challenges that need to be thoroughly investigated. READ MORE

4. 3. Numerical simulations oflovastatin crystallization in aT-shaped 2D mixer

   University essay from KTH/Optimeringslära och systemteori

   Author : Anton Bergman; [2023]
   Keywords : ;

   Abstract : The rise of battery driven technology and the strive towards circular economy calls for the indefinite recycling of metals used in batteries. To be able to study and optimize the processes used in recycling, mathematical models are required. READ MORE

5. 4. Computational Analysis of Spray Deflector Designs

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Osman Gyokhan Ali; [2023]
   Keywords : Planing Hulls; Spray Deflector; Hull Modification; Computational fluid dynamics CFD ; resistance; trim angle; heave; CD-adapco Star CCM ; Numerical Ventilation; Phase Replacement; Modified HRIC Scheme; Volume Fraction Source Term; Reynolds averaged Navier-Stokes RANS ; Volume of Fluid VOF ; SST K-Omega Turbulence Modelling; Höghastighetshantverk; modelldesign; spraydeflektor;

   Abstract : 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. READ MORE

6. 5. 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
