  1. 11. CFD analysis of nozzle effect on jet formation

    Master-uppsats, KTH/Mekanik

    Författare :Mustafa GÜDÜCÜ; [2015]
    Nyckelord :;

    Sammanfattning : This project is concerned with CFD simulations of jets issued from elliptical nozzles. The investigated jet flow in this project is turbulent flow emanating from microscopic nozzles into a combustion chamber. LÄS MER

  3. 12. Accuracy of transient versus steady state forces on a rudder operating in a propeller slipstream

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Erik Löfgren; [2015]
    Nyckelord :Unsteady flows; rudders; propellers; fluid mechanics; performance prediction; unsteady aerofoils;

    Sammanfattning : In computational fluid dynamics (CFD), a transient simulation is in general more costly than computing the steady state of the system, if such a state exists. The velocity field produced by the propeller blades upstream of a rudder is transient in nature, and rudder design using CFD may therefore become very time-consuming. LÄS MER

  4. 13. Bostadsbubbla på den svenska marknaden?

    Kandidat-uppsats, KTH/Fastigheter och byggande

    Författare :Oskar Rosell; [2015]
    Nyckelord :housing bubble; housing boom; housing; Bostadsbubbla; bostadsmarknad; prisfall;

    Sammanfattning : Svenska bostadsmarknaden har de senaste åren varit ett hett diskussionsämne i media. Kanske beror det på att bostadspriserna har stigit i en snabbare takt de senaste 15 åren jämfört med de senaste 60 åren, vilket har skapat diskussioner kring en eventuell prisbubbla som skulle orsaka stora problem för många.

  5. 14. Simulation of Microbubbles during the Initial Stages of Breakdown in Cyclohexane

    Kandidat-uppsats, KTH/Fysik

    Författare :Henrik Frid; [2013]
    Nyckelord :;

    Sammanfattning : The formation of a vapor microbubble has previously been suggested to be the initial mechanism in the process of dielectric failure of dielectric liquids. The bubble is generated by a rapid, highly localized heating of a volume close to a highly stressed electrode, caused by electric currents in the liquid at high voltages. LÄS MER

  7. 15. Indicators for Bubble Formation in Housing Markets

    Master-uppsats, KTH/Bygg- och fastighetsekonomi

    Författare :Björn Sjöling; [2012]
    Nyckelord :Prediction of property markets; indicators; bubbles; variable rate interest rates;

    Sammanfattning : It widely is assumed that property markets can be predicted and to be able to make forecasts, concerning future housing prices, a number of different indicators are used. But if it possible to know the future today, why do we still experience bubbles in housing markets? To answer this question the reliability of four of the most commonly used indicators were tested for the time period between 2000 and 2010. LÄS MER
