  1. 1. Dynamic Modeling of Heat Power System : Modeling of a Heat Power System Using Physical and Data-driven Methods and Investigation of a Moving Boundary Method

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Albin Gustafsson; [2023]
    Keywords : System identification; Dynamic modeling; Organic Rankine cycle; Moving boundary; Thermodynamics.; System identifikation; Dynamisk modellering; Organisk Rankinecykel; Rörliga randvillkor; Termodynamik.;

    Abstract : Our society is becoming more and more electrified every day. However, a significant portion of the world’s electricity generation relies on the combustion of fossil fuels to produce heat, which is subsequently harnessed to generate electricity. One way of generating electricity from heat is by utilizing a Rankine cycle. READ MORE

  3. 2. An experimental study of surface coatings to limit the impact of frosting

    University essay from KTH/Energiteknik

    Author : Carl Andersson; [2018]
