  1. 1. Design and Implementation of Object-Oriented Model Libraries using Modelica

    University dissertation from Department of Automatic Control, Lund Institute of Technology (LTH)

    Author : Hubertus Tummescheit; Lund University.; Lunds universitet.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modeling languages; thermo-fluid systems; process modeling; process control; control systems; thermo-hydraulic systems; non-linear models; model library design; object-oriented; modeling; simulation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : This thesis describes basic models for thermo-fluid systems and the implementation of the models using a flexible object-oriented structure in the ThermoFluid library. Model libraries provide an excellent way to package engineering knowledge of systems to be reused by non-experts. READ MORE

  3. 3. Aerothermodynamics and exergy analysis in turbocharger radial turbine

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Shyang Maw Lim; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pulsatile exhaust flow; turbine; turbocharger; Detached Eddy Simulation; heat transfer; exergy; Teknisk mekanik; Engineering Mechanics;

    Abstract : Coupling of turbomachine to reciprocating automotive engine in turbocharging leads to complex fluid flow and thermal characteristics in the turbine. Some undesirable characteristics include heat transfer, flow pulsation and secondary flow due to the complex geometry of the upstream exhaust manifold. READ MORE
