  1. 21. Modeling the Effects of a MitraClip™ : Simulations of the Blood Flow in the Left Ventricle After MitraClip™ Therapy

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Samuel Eriksson Lidbrink; Ludvig Lindström; [2021]
    Keywords : ;

    Abstract : As heart disease is the leading cause of death worldwide it is of great interest to improve our understanding and treatment of different heart conditions. One step in doing this might be developing computational models of how the blood flows in the heart. This paper builds upon prior models by Larsson et al. (2017) and Svelander et al. READ MORE

  3. 22. 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

  4. 23. CFD Simulation of Particles in Pipe Flow and Mixing Tank

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Aljaz Janic; [2020]
    Keywords : Multiphase flow; particles; TetraPak; mixing tank; pipe flow;

    Abstract : This project aimed to investigate the capability of the STAR CCM+ software when predicting the flow with particles using Lagrangian Particle Tracking and Discrete Element Method. The first part pertained to rectangular channel flow, with ratio between height of the channel and particle diameter (2h/Dp ) of 15. READ MORE

  5. 24. A Study in Solar Housing Technology: The Impact of Trombe Walls in Ladakh

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

    Author : Sebastian Arora-Jonsson; [2020]
    Keywords : ;

    Abstract : The aim of this bachelor’s thesis is to examine the effect of installing a Trombe Wall in houses in Ladakh, India, and to evaluate its impacts for energy-saving, improvement in life quality, and its financial viability. Trombe Walls are a passive solar technology that use a dark wall with a glass covering to slowly heat living spaces by storing solar energy. READ MORE

  6. 25. COMPUTATIONAL FLUID DYNAMICS MODELING FOR BENT SPILLWAY CHANNEL : Numerical validation of a small scale physical model

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Mikael Björnfot; [2020]
    Keywords : Energy; CFD; Hydropower plant; Energi; Vattenkraft;

    Abstract : Hydropower plants with spillways exposed to high pressures because of large discharges can result in a dam failure which ultimately results in devastating consequences. Therefore properly designed and constructed spillways are important. READ MORE
