  1. 1. Investigation of different ventilation profiles to avoid stratification in Nearly Zero Energy Buildings

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Alazne Irene Varela Santana; [2023]
    Nyckelord :stratification; water model; comfort; mixing; temperature; potential energy; net zero energy building;

    Sammanfattning : This research paper examines possible solutions for the problems that warm air heating is suffering in Nearly Zero Energy Buildings. These NZEBs are passive houses constructed to have high energy efficiency where the quantity of power used is equal to the power created annually, produced locally or in the surroundings by renewable energy sources.

  3. 2. Experimental Study of Flow Fields in Moving Bed Biofilm Reactors

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Shea Nee Chew; [2023]
    Nyckelord :Moving bed biofilm reactors; Biofilm carriers; Mechanical mixing; Mixer configurations; Carrier mixing; Biofilmsreaktorer med rörlig bädd; Biofilmsbärare; Mekanisk blandning; Blandarkonfigurationer; Bärarblandning;

    Sammanfattning : With the rise in global energy prices, as well as energy consumption being the largest source of greenhouse gas emissions, biofilm-based systems utilized for wastewater treatment, such as moving bed biofilm reactors (MBBRs), have grown in popularity for their lower energy consumption compared to conventional activated sludge processes. However, this technology requires large amounts of energy to constantly distribute and suspend its biofilm carrier within the reactor by either aerators or mechanical mixers. LÄS MER

  4. 3. Oil Autonomy of a Turbojet

    Master-uppsats, KTH/Flygdynamik

    Författare :Florian Steiner; [2022]
    Nyckelord :Fluid Mechanics; Turbojet; Oil circuit; Fluid Mekanik; Turbojet; Oljekrets;

    Sammanfattning : The oil circuit of a jet engine is required to lubricate and cool mechanical parts. The oil is pumped from the oil tank and flows through heat exchangers. Then it is injected on the bearings for lubrication and cooling, before being scavenged at the bottom of the sumps and finally flows back to the oil tank. LÄS MER

  5. 4. Stabilisering och solidifiering av muddermassor : En studie av det praktiska utförandet

    M1-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Författare :Albin Holmgren; Daniel Karlsson Fagerberg; [2022]
    Nyckelord :Stabilisering; solidifiering; förorenade muddermassor; sediment; S S; Köping; hamn;

    Sammanfattning : Enligt en inventering som gjorts av 40 svenska hamnar kommer minst 2,5 miljoner kubikmeter förorenat sediment behöva tas omhand de närmaste åren (Holm, 2011). Stabilisering och solidifiering är idag det mest aktuella alternativet till deponering på land och dumpning till havs, alternativ som enligt avfallslagen i största möjliga mån bör undvikas. LÄS MER

  7. 5. Predict Flow Field and Mixing Time for High-Shear Mixers Using CFD

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :David Fransson; Eric Kihlman; [2021]
    Nyckelord :CFD; High-Shear Mixer; Energy Science; Simulation; Mixing time; blend time; Flow Field; Technology and Engineering;

    Sammanfattning : Batch high-shear mixers are used in a variety of different processing industries,such as the pharmaceutical, chemical and food industries. One company that utilize this type of mixers is Tetra Pak. High-shear mixers can be used for many different mixing scenarios, but only liquid-liquid mixing is discussed in the thesis. LÄS MER
