  1. 1. Automated Solar Panel Shield : An IoT Approach

    Kandidat-uppsats, Blekinge Tekniska Högskola

    Författare :Raghu Vamsi Sai Rangannagari; Sri Phani Deverakonda; [2022]
    Nyckelord :Arduino Uno; Weather monitoring; Sensors; Solar panel; Shield;

    Sammanfattning : Context: Solar panels are exposed to different weather conditions and get damaged. Sand storms and hail storms could cause serious damage. However, they need to be used for human survival in almost every harsh condition possible. Objectives: Our goal is to design and create a working prototype of an automated solar panel shield.

  3. 2. Turbulence Intensity Measurements in a High-Pressure Gas Turbine Stage

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Ettore Scami; [2022]
    Nyckelord :Turbulence Intensity; turbine; stage efficiency; grid; turbomachinery; length scales;

    Sammanfattning : This Thesis work focused on the acquisition and evaluation of data on mean velocity, turbulence intensity and length scales obtained via hot wire measurements in a high pressure single-stage land-based turbine available at the Department of Heat and Power Technology in KTH. Turbulence was generated by the use of grids and twoprobes, upstream and downstream of the turbine stage, were used. LÄS MER

  4. 3. Noggrannhet i luftflödesmätare i tre VAV-apparater samt anemometer- och stosmetod : En experimentell studie med låga luftflöden

    Kandidat-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Lina Lelander; [2021]
    Nyckelord :ventilation; VAV-system; VAV-apparat; stos; anemometer; låga luftflöden; luftflö-desmätning; mätosäkerhet;

    Sammanfattning : En byggnad bör uppfylla kraven gällande energianvändning och god inomhusmiljö. Byggnadens ventilationssystem arbetar med att upprätthålla god luftkvalitet samt effektiv energianvändning. LÄS MER

  5. 4. Analysis of wall-mounted hot-wire probes

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Alvisi Alex; Perez Adalberto; [2020]
    Nyckelord :Turbulent Boundary layer; Turbulent Channel Flow; Hot Wire Anemometer; Direct Numerical Simulations; Immersed Boundary Method;

    Sammanfattning : Flush-mounted cavity hot-wire probes have been around since two decades, but have typically not been applied as often compared to the traditional wall hot-wires mounted several wire diameters above the surface. While the latter suffer from heat conduction from the hot wire to the substrate in particular when used in air flows, the former is belived to significantly enhance the frequency response of the sensor.

  7. 5. Experimental investigation of ventilation performance of corner placed stratum ventilation in an office environment

    Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Gasper Choonya; [2019]
    Nyckelord :Stratum ventilation; local air change index; air change efficiency; ventilation effectiveness; draught rate; percentage dissatisfied; heat removal effectiveness;

    Sammanfattning : Energy use in buildings account for about one third of the total global energy supply and contributes as much as 30% of the anthropogenic greenhouse gas emissions. It is estimated that energy use in buildings will increase to 67% by 2030. LÄS MER
