  1. 11. Development of a 1D to 3D CFD couplingmethodology on an inlet manifold

    Master-uppsats, KTH/Mekanik

    Författare :Andreas Johansson; [2018]
    Nyckelord :;

    Sammanfattning : We investigate the coupling between 3D simulations of the flow in an engine manifold with simplified 1D models of the engine performance. The inlet manifold in an existing 1D engine model is replaced with a more sophisticated CFD manifold simulation. The rest of the 1D system is left untouched. LÄS MER

  3. 12. Placing VOC Sensors forAssessing Air Quality : A CFD Study of Indoor VOC Distribution

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Sara Högdahl; [2018]
    Nyckelord :;

    Sammanfattning : The Swedish Obligatory Ventilation Control (OVK) was established to ensure that ventilation systemsare clean and work according to design. The control system of today is however not perfect, and thereare many aspects of OVK which could be approached differently for improved efficiency and occupanthealth. LÄS MER

  4. 13. CFD on Open Wet Cutch to Reduce Drag Losses

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Rimmie Duraisamy; [2017]
    Nyckelord :transmission; clutch; multiphase CFD; grooves; oil dissipation; drag losses; transmission; koppling; Multifas-CFD; spårmönster; undanträngning av oljan; strömningsförluster;

    Sammanfattning : As the need for highly efficient transmission systems increase, it is imperative to have lower fuel consumption levels. Hence, it becomes crucial to investigate and understand reasons behind various losses occurring within the system. Clutches and gears contribute to the major losses within a transmission system.

    Författare :Mia Holappa; [2017]
    Nyckelord :NOx; förbränning; rosterpanna; simulering; CFD;

    Sammanfattning : Vasa värme är ett företag som producerar och levererar fjärrvärme. Anläggningen i Kalixomfattar bland annat en 10 MW rosterpanna, FBP2, som eldas med fuktigt biobränsleoch Vasa värme vill sänka sina NOx-emissioner från denna panna. LÄS MER

  7. 15. Design Optimization of Spillways at Baihetan Hydroelectric Dam

    Master-uppsats, KTH/Energiteknik

    Författare :Jack Lönn; Oskar Dahl; [2016]
    Nyckelord :;

    Sammanfattning : China’s economic prosperity has led to a massive development in the hydropower sector. The Baihetan hydropower project is an ongoing construction and will become the third largest hydroelectric power plant in the world in regards to generating capacity and is projected to be finished in the year 2020.
