  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

  2. 2. Numerical Study on Air Demand of Free Surface Flows in a Discharge Tunnel

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Jonathan Barassa; Rickard Nordlöf; [2020]
    Keywords : Computational Fluid mechanics; Hydropower; Air demand; Free surface flows; ANSYS Fluent;

    Abstract : Aeration issued through a ventilation shaft is an important measure to prevent cavitation and large gauge pressure in flood discharge tunnels. In order to dimension the ventilation shaft appropriately, itis necessary to have a good understanding of the air-water flow in the tunnel. READ MORE

  3. 3. Numerical ice sheet modelling using FEniCS

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : André Löfgren; [2019]
    Keywords : ;

    Abstract : The increase in computational power in the last 20 years has made it feasible to solve the full Stokes equation for ice flow, using finite element methods (FEM). However, the numerical properties of these equations remains largely unknown. This is due to their nonlinear nature, which makes them hard to analyze mathematically. READ MORE

  4. 4. Planning support for reducing risks related to flooding : A case study of flood response in Kista residential area and Igelbäcken stream, Sweden

    University essay from KTH/Mark- och vattenteknik

    Author : Kajsa Lundgren; [2017]
    Keywords : Planning support; blue green solutions; hydrodynamic modelling; MIKE FLOOD; climate change adaption; land use change; Planeringsstöd; blå-gröna lösningar; hydrodynamiskmodellering; MIKE FLOOD; klimatanpassning; markanvändning;

    Abstract : Flooding has been identified as the most widespread and most frequently occurring natural disaster by the United Nation. Sweden is no exception when it comes to being affected by flooding, and several major flood events have been seen in recent years. READ MORE

  5. 5. Study on free-surface aeration with high-velocity air-water flows in open-channels

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Belkiz Hasan; Paulo Monsalve; [2017]
    Keywords : ;

    Abstract : China’s biggest source of the renewable energy is hydropower, with a share of 85 %, in 2013, of the total renewable power generation. For the tenth sequential year, China has maintained the country’s leading role in global hydropower development by installing more hydropower plants than the rest of the world combined. READ MORE
