  1. 1. A VVER1000 primary side model in Apros

    Master-uppsats, KTH/Fysik

    Författare :Karl-Edvin Strand; [2023]
    Nyckelord :Apros; VVER1000; PWR; Modelling; HPIS; Boron acid; Apros; VVER1000; PWR; Modellering; HPIS; Borsyra;

    Sammanfattning : Nuclear power plants generate electricity by means of splitting atoms. The basic safety requirements and objectives are to protect the people, society, and the environment from radiological accidents, limit harmful effects of ionizing radiation during operation and take all reasonable practical steps to prevent radiological accidents.

  3. 2. Predicting Processing and Filling Equipment with Complex Food Rheology

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

    Författare :Ayupry Diptasari; Cynthia Andriani; [2020]
    Nyckelord :filling behavior responses; pressure drop; rheology parameters; rheopexy; thixotropy; time-dependent; food engineering; livsmedelsteknik; Technology and Engineering;

    Sammanfattning : As a food processing lines manufacturer with diverse product complexity, an understanding of fluid dynamics in a pipe system corresponding to the rheological properties and flow behavior is substantial. This will be beneficial to design suitable equipment and prevent processing-related issues, i.e. LÄS MER

  4. 3. EXPERIMENTAL STUDY ON PRESSURE LOSSES IN ADDITIVELY MANUFACTURED AND MACHINED ORIFICES : A rectangular geometry of additively manufactured MA 247 orice and a circular geometry ofmachined AW-6082 T6 orifice study

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Jayadev Nambisan; [2020]
    Nyckelord :Cooling; Fluid Dynamics; Additive Manufacturing; Pressure Losses; Fluid Dynamics Testing; Machining; Gas Turbines; Gas Turbine Cooling; Nouveau Geometries;

    Sammanfattning : Gas turbine components for cooling purposes including other unique and complex three-dimensional designs could be made explicitly possible through additive manufacturing using SLM technology in contrary to the conventional machining processes. Nevertheless, the surface roughness and subsequently the friction factor governs thepressure drop in these components implicitly, thus, influencing the secondary air flow system of a gas turbine.

  5. 4. Battery Energy Storage Systems as an alternative to gas turbines for the fast active disturbance reserve

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Ludvig Wingren; Jonas Johnsson; [2018]
    Nyckelord :BESS; Energy Storage; Batteries; mFFR; Fast Active Disturbance Reserve; Gas Turbines; Technology and Engineering;

    Sammanfattning : Power systems operate at a specific frequency and constantly require a balance between production and consumption of electricity in order to maintain the frequency within a certain interval. Larger frequency deviations can cause blackouts or damage equipment connected to the grid. LÄS MER

  7. 5. Optimeringsverktyg för automatisk planering och reglering av produktion i småskaliga vattenkraftverk

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Jenny Möller; Johan Wiklund; [2018]
    Nyckelord :optimisation tool; small-scale hydropower plant; production planning; control; optimeringsverktyg; småskalig vattenkraft; produktionsplanering; reglering;

    Sammanfattning : Småskaliga vattenkraftverk regleras vanligtvis med avseende på vattennivån i magasinet eller vattenflödet, utan hänsyn till efterfrågan på elkraft. Examensarbetet utfördes på uppdrag av Fortum Generation som önskade att undersöka möjligheten att istället automatiskt optimera planeringen och regleringen av de småskaliga vattenkraftverken med hänsyn till prisbild, verkningsgrad, vattensituation, miljödomar, miljöhänsyn samt mekaniskt slitage.
