    Sammanfattning : Roterugnar är cylindriska kärl som används för att höja materials temperaturer i en kontinuerlig process som kallas för kalcinering. Roterugnar kan tillämpas i olika processer såsom reduktion av oxidmalm samt återvinning av farligt avfall. LÄS MER

  3. 2. Värmeöverföring mellan två zoner i en bubblande fluidiserad bädd

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Christian Stigsson; [2018]
    Nyckelord :Heat transfer; fluidized beds; multi-staging; Eulerian-Eulerian two-fluid; Technology and Engineering;

    Sammanfattning : In this Master's thesis, the heat transfer between two zones in a bubbling fluidized bed and the resultant temperature field were examined using a laminar Eulerian-Eulerian two-fluid model in computational fluid dynamics. The purpose was to estimate the thermal potential to multi-stage a combined heat and power boiler by integration therein of a communicating gasification reactor, which utilizes heat from the combustion, and to analyze how different construction parameters influence the homogeneity of the gas temperature field.

  4. 3. Volume Kinetic Models for Perioperative Fluid Therapy

    Kandidat-uppsats, KTH/Skolan för teknik och hälsa (STH)

    Författare :Pehr Wessmark; Viktor Winther; [2015]
    Nyckelord :Volume kinetics; Population volume kinetics; Fluid therapy; Interstitial fluid expansion; 0.9% saline;

    Sammanfattning : Intravenous fluid infusion during surgeries is based on clinical practice guidelines. Many factors impact the fluid distribution in the body, mainly the effect of anesthetic gases and surgical stress. Volume kinetics is a method to simulate the distribution and elimination of infusion fluids by considering the dilution of plasma over time. LÄS MER
