  1. 6. Micro-architectured materials for thermal management : Porous graphite/graphene boiling enhancement structures

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Melody Ghaderidosst; [2022]
    Keywords : Microarchitecture; TPMS; Gyroid; thermo-mechanical; computational homogenization; graphite; graphene;

    Abstract : The convergence of the digital and physical world encourages advances in high-speed telecommunication and fifth generation technology. Two-phase heat transfer systems are common engineering solutions. However, due to the large frequency spectra in 5G, the systematic heat generation increases requiring more efficient thermal management. READ MORE

  3. 7. Neural Network Based Model Predictive Control of Turbulent Gas-Solid Corner Flow

    University essay from Uppsala universitet/Signaler och system

    Author : Simon Wredh; [2020]
    Keywords : computational fluid dynamics; machine learning; system identification; control theory; multi-phase flow; gas-solid flow; rans; lagrangian particle tracking; neural network; model predictive control; bio-aerosol;

    Abstract : Over the past decades, attention has been brought to the importance of indoor air quality and the serious threat of bio-aerosol contamination towards human health. A novel idea to transport hazardous particles away from sensitive areas is to automatically control bio-aerosol concentrations, by utilising airflows from ventilation systems. READ MORE

  4. 8. Development of waterborne and mild curing DWRs, formulated with fully bio-based substances

    University essay from KTH/Fiber- och polymerteknologi

    Author : Johannes R. S. van Overmeeren; [2020]
    Keywords : Durable water repellents; Bio-based; Biodegradable; Two-phase systems; Fluorine-free; Functional textile finishes; Vattenavvisning; Bio-baserad; Biologiskt nedbrytbar; Fluorkarbonfri; Funktionella textilbehandlingar;

    Abstract : ”Durable water repellents (DWR) är textilimpregneringar som bidrar med vattenavvisande egenskaper som håller länge på funktionella tyg. Tyvärr är dessa hydrofobiska ytbehandlingar vanligtvis en källa till skadliga och persistenta kemikalier och de även är producerade från fossilbaserade resurser. READ MORE

  5. 9. Design Investigation into Liquid Oxygen Vaporisation Systems : Atomisation and Heat Loads

    University essay from KTH/Energiteknik

    Author : Borbala Bernus; [2020]
    Keywords : LOx; gasification; two-phase CFD simulation; rapid oxidation; rocket; cryogenic; hybrid; atomisation; LOx; förgasning; 2-fas CFD-simulering; snabb oxidation; raket; kryogen; hybrid; atomisering;

    Abstract : Computational Fluid Dynamics (CFD) simulations are presented within this study for super-cooled liquid oxygen atomisation and gasification in a subcritical chamber operating at 1MPa. Relatively low cost simulation techniques have been used and their accuracy evaluated. READ MORE

  6. 10. A Numerical Analysis on the Effects of Using CO2 as a Driving Fluid for a Geothermal Plant

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : David Bennich; [2020]
    Keywords : reinjection; two-phase flow; geothermal energy; CO2 sequestration; iTOUGH2; ECO2N; återinjektion; tvåfasflöde; geotermisk energi; koldioxidlagring; iTOUGH2; ECO2N;

    Abstract : To limit the effect of global warming society needs clean energy sources and to reduce emissions of greenhouse gases into the atmosphere. By combining carbon capture and storage technologies together with geothermal power production it is possible to gain fossil free energy while potentially storing CO2 at the same time. READ MORE
