  1. 1. Boundary Layer Studies above lake Erken using Modelling and UAV

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

    Author : Oliver Nordvall; [2020]
    Keywords : Internal Boundary Layer; UAV; Sea Breeze Circulation; Numerical Simulation; WRF; lake Erken; Internt gränsskikt; UAV; Sjöbris; Numerisk simulation; WRF; Erken;

    Abstract : Internal boundary layers (IBLs) above lakes, created primarily by the autumn differential of land and lake surface temperatures, present a unique way of studying the lake-atmosphere coupling within the boundary layer. The small and mobile unmanned aerial vehicles (UAVs) contribute to new research areas within the boundary layer, offering high spatial resolution measurements to complement already existing observations.

  3. 2. Tesla Valve for Hydrogen Decompression: Fluid Dynamic Analysis

    University essay from KTH/Skolan för industriell teknik och management (ITM); KTH/Skolan för industriell teknik och management (ITM)

    Author : Elias Bäckman; Mathilda Willén; [2019]
    Keywords : Decompression; Hydrogen gas; Tesla valve; no-moving parts; CFD; valve-to-valve; 压降；氢气；特斯拉阀；无可动阀芯；计算流体动力学；级间距; Decompression; Hydrogen gas; Tesla valve; No-moving parts; CFD; valve-to-valve;

    Abstract : Människans påverkan på växthuseffekten har under de senaste åren varit en mycket aktuell fråga. Det är många olika faktorer som bidrar till ett negativt avtryck på miljön, där ett stort bidrag kommer från sektorn bilindustri. Majoriteten av dagens bilar drivs på fossila bränslen som genererar skadande utsläpp på miljön. READ MORE

  4. 3. Improving Short-Range Cloud Forecasts in Harmonie-Arome Through Cloud Initialization Using Mesan Cloud Data

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

    Author : Joakim Pyykkö; [2019]
    Keywords : cloud initialization; HARMONIE-AROME; MESAN; satellite product; synoptic weather station;

    Abstract : Previous studies, such as van der Veen (2012) and White et al. (2017), have demonstrated the potential of using measurement-based cloud data to improve Numerical Weather Prediction (NWP) based cloud forecasts. This can be done through cloud initialization; a process of injecting cloud data after the regular data assimilation in an NWP model. READ MORE

  5. 4. Fire Safety of Facades

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Bogdan-Grigore Branisteanu-Albulescu; [2019]
    Keywords : polystyrene; graphene; façade; pyrolysis; Technology and Engineering;

    Abstract : Façade fires are a big concern due to past incidents and the large number of victims encountered. Vertical flame spread mechanism specific to this type of fires is a complex phenomenon with parameters that are often difficult to be coupled. READ MORE

  6. 5. Interscale transport of Reynolds stresses in wall-bounded flows

    University essay from KTH/Skolan för teknikvetenskap (SCI); KTH/Skolan för teknikvetenskap (SCI)

    Author : Gioele Ferrante; Andres Morfin; [2019]
    Keywords : Reynolds Stress; Zero-Pressure Gradient Turbulent Boundary Layer; Turbulent Couette Flow; Inverse Interscale Transport; Energy Cascase; Wall-bounded Flows; Direct Numerical Simulation; Large Eddy Simulation.;

    Abstract : Couette, pipe, channel, and zero-pressure gradient (ZPG) turbulent boundary layer (TBL) flows have classically been considered as canonical wall-bounded turbulent flows since their near-wall behavior is generally considered to be universal, i.e. invariant of the flow case and the Reynolds number.
