  1. 21. Dynamic Modeling of Target's Cooling Systems

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Maximilian Cahlin; [2021]
    Nyckelord :Dynamic modeling; Modelica; Dymola; Fluid mechanics; Thermodynamics; Technology and Engineering;

    Sammanfattning : The thermal energy generated from the spallation process in the ESS facility must be cooled by cooling systems in order to ensure safe operation of the facility. It is of interest to understand what operating conditions of the cooling systems will ensure this safety for both stationary conditions and transient events. LÄS MER

    Sammanfattning : Scania works continuously to develop internal combustion engines and after treatment systems which can achieve low pollutant emissions and high efficiency. A major principal that Scania adopted for this goal is the Simulation Driven Development (SDD) process. LÄS MER

  4. 23. A Nonlinear Reservoir Model to Simulate Blue-Green Stormwater Systems – An Application to Augustenborg Catchment in Malmö, Sweden

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Emmanuel Ekwu; [2021]
    Nyckelord :Blue-green stormwater control; Nonlinear reservoir routing model; Stormwater; Modelling; Calibration; Water engineering; Technology and Engineering;

    Sammanfattning : The increasingly rapid urbanization has led to vast impervious surface areas in the urban environment. This situation of impervious surfaces has increased the surface temperature and interrupted the natural water circle, which has negatively impacted the urban environment. LÄS MER
