  1. 1. Water born cooling of closed greenhouses : An enclosed vertical water curtain cooling system

    Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Ahmad Kamal; [2022]
    Nyckelord :Greenhouses; Water born cooling; Enclosed water curtain; radiative cooling; Surplus heat energy;

    Sammanfattning : The greenhouses play a key role in food sustainable production, the purpose of the greenhouses is to make an artificial suitable environment to grow different kinds of plants. The cost of energy used in the greenhouses to ensure the optimum temperature, humidity, and CO2 concentration, makes up a large part of the final cost of food. LÄS MER

  3. 2. Ly-α Dayglow on Uranus : Radiative Transfer Modelling

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jahangir Jazayeri; [2021]
    Nyckelord :Uranus; Lyman-alpha; Ly-α; resonant scattering; Rayleigh scattering; interplanetary medium; ultraviolet; hydrogen; methane; parameter study; limb brightening; Voyager 2; Ultraviolet Spectrometer;

    Sammanfattning : Uranus is one of the least explored planets in our solar system. Event though the Uranian Ly-α emission has been a subject of study for decades, there is not a consensus on the sources contribution to the total signal. LÄS MER

  4. 3. Weather Influence on LiDAR Signals using the Transient Radiative Transfer and LiDAR Equations

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Marcus Hedlund; [2020]
    Nyckelord :Radiative transfer; LiDAR; Transient radiative transfer;

    Sammanfattning : The ongoing development of self driving cars requires accurate measuring devices and the objective of this thesis was to investigate how di↵erent weather will affect one of these devices, known as a LiDAR. A LiDAR uses pulsed laser light to measure the distance to an object. LÄS MER

  5. 4. Thermal gas radiation modelling for CFD simulation of rocket thrust chamber

    Master-uppsats, KTH/Kraft- och värmeteknologi
