  2. 21. Computational hydrodynamics applied to an America's Cup class keel - best practice and validation of methods

    Author : Sofia Werner; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; America s Cup; induced drag; wind tunnel; winglet; validation; keel; vortex drag; wake survey;

    Abstract : Numerical predictions of the flow around yacht keels can be performed with various types of methods. In this work computational fluid dynamic (CFD) computations are validated against wind tunnel studies of an America's Cup Class keel with the purpose of investigating the accuracy that can be achieved with CFD, which methods that are suitable and how they should be used in the best way.

  4. 22. Parameter estimation in heterogeneous catalysis

    Author : Jonas Sjöblom; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; microkinetic modelling; Jacobian; Parameter estimation; Latent Variable models; Design of experiments; heterogeneous catalysis; sensitivity analysis; Experimental design;

    Abstract : The detailed modelling of heterogeneous catalytic systems is challenging due to the unknown nature of new catalytic materials as well as the often required transient nature of the resulting models. Thus, this thesis deals with the methodologies involved in the kinetic modelling of heterogeneous catalysis and in particular NOx reduction systems. READ MORE

  5. 23. Wind Turbine Models for Power System Stability Studies

    Author : Abram Perdana; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fixed-speed; variable-speed; validation; modelling; power system stability; frequency stability; aggregated model; wind turbine; voltage stability;

    Abstract : The purpose of this thesis is to develop dynamic models of wind turbines for power system stability studies. More specifically, the wind turbine models are mainly intended for voltage and frequency stability studies. READ MORE

  6. 24. District heating and cooling systems transition : Evaluation of current challenges and future possibilities

    Author : Marwan Abugabbara; Avdelningen för Installations- och klimatiseringslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-domain modelling; Modelica; Heat pumps; 5GDHC; BLTN; Validation;

    Abstract : District heating and cooling systems offer a cost-effective and secure supply of heating and cooling to connected buildings. They are widely recognised as a key solution to decarbonise the building sector due to their high potential of integrating renewable energy sources. READ MORE

  7. 25. Characterization of suspended particulate matter from freshwater : validation of a field filtration technique

    Author : Fredrik Ödman; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Abstract : A field filtration method for the concentration and separation of suspended particulate matter (SPM) from freshwater systems and the subsequent determination of major, minor, trace and ultra trace elements (Al, As, Ba, Be, Ca, Cd, Co, Cr, Cs, Cu, Fe, Ga, Hf, K, Mg, Mn, Mo, Na, Nb, Ni, P, Pb, Rb, S, Sb, Sc, Si, Sn, Sr, Ta, Th, Ti, Tl, U, V, W, Zn and Zr) is validated with respect to detection limits, precision, and bias. The validation comprises the whole procedure including filtration, sample digestion and instrumental analysis. READ MORE
