  1. 16. Simulation of Leachate Generation from a Waste Rock Dump in Kiruna Using HYDRUS-1D

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Aryani Atmosudirdjo; [2019]
    Nyckelord :Hydrus-1D; matrix flow; leachate; unsaturated flow; waste rock dump;

    Sammanfattning : The percolation of water through waste rock dumps at mine sites can lead to the production of a leachate with high concentrations of dissolved metals, sulfate and nitrogen compounds. It is important to understand how water flows in waste rock dumps in order to predict the environmental impact of this leachate on recipients. LÄS MER

  3. 17. Large Eddy Simulation of Turbulent Flow over a Backward-Facing Step

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Edmond Shehadi; [2018]
    Nyckelord :;

    Sammanfattning : This work studies the effect of grid resolution and subgrid scale modeling on the predictive accuracy of Large Eddy Simulation. In particular, the problems considered are: turbulent flow over a backward-facing step and fully-developed turbulent channel flow. LÄS MER

  4. 18. Virtual Sensor Describing the Intake Manifold Pressure Close to the Cylinder Ports

    Master-uppsats, KTH/Förbränningsmotorteknik

    Författare :Sotirios Tsironas; [2018]
    Nyckelord :;

    Sammanfattning : Ökad efterfrågan på effektivare motorer och strängare lagstiftning rörande avgasutsläpp kräver en noggrannare styrning av motorns driftsparametrar. Denna styrning är mestadels baserad på ett antal fysiska sensorer som spelar en viktig roll vid utsläppsrelaterad feldiagnostik. LÄS MER

  5. 19. Estimation of Engine Gas Temperatures During Pressure Transients

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Marcus Wallson; [2018]
    Nyckelord :;

    Sammanfattning : Coming stringent regulatory emissions requirements with Real Driving Emissions testing amplifies the need for efficient engine control at all driving scenarios. This thesis has investigated the air-flow transients that appears when changing the throttle position very fast, such as at a stop sign. LÄS MER

  7. 20. Turbo Heat Transfer Modeling for Control

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Anon Nordlöf; John Lundqvist; [2018]
    Nyckelord :Turbo; Control; Heat; transfer; Volvo; Liu;

    Sammanfattning : The demand for lower emission engines forces the car industry to build moreefficient engines. Turbocharged engines are on the rise, and better understandingof the heat transfer and efficiency of the turbocharger is needed to build better ones. LÄS MER
