  1. 1. Approaches for improving the rheological characterization of fermented dairy products

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Abdulrahman Muhammad; [2020]
    Nyckelord :food engineering; livsmedelsteknik; Technology and Engineering;

    Sammanfattning : Fermented dairy products are wildly consumable products in today societies, and these products are known for their unique rheological properties due to the complex structural systems they possess. The simplest rheological model for describing yogurt behavior is the Power Law model, but this model parameters are not sufficient for describing the complex behavior during flow and filling.

    Sammanfattning : Comprehensive rehabilitation projects of dam spillways are made in Sweden, due to stricter dam safety guidelines for their discharge capacity. The Piano Key Weir (PKW) is an innovative design which has proven effective through several renovation projects made in many countries including France. LÄS MER

  3. 3. Aircraft Winglet Design

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI); KTH/Skolan för teknikvetenskap (SCI)

    Författare :Hanlin GongZhang; Eric Axtelius; [2020]
    Nyckelord :;

    Sammanfattning : Aerodynamic drag can be decreased with respect to a wing’s geometry, and wingtip devices, so called winglets, play a vital role in wing design. The focus has been laid on studying the lift and drag forces generated by merging various winglet designs with a constrained aircraft wing. LÄS MER

  5. 5. Methods to Predict Hull Resistance in the Process of Designing Electric Boats

    Master-uppsats, KTH/Marina system; KTH/Marina systemKTH/FlygteknikKTH/Farkost- och flygteknik

    Författare :Felicia Ahlstrand; Jacob Kuttenkeuler; [2020]
    Nyckelord :;

    Sammanfattning : Combustion engines in boats cause several environmental problems, such as greenhouse gas emissions and acidication of oceans. Most of these problems can be reduced by replacing the combustion engines with electric boats. LÄS MER
