  1. 1. LES Simulation of Hot-wire Anemometers

    Magister-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Assiye Süer; [2017]
    Nyckelord :Hot-wire anemometer; Hot-film anemometer; Computational Fluid Dynamics; Mars Science Laboratory; MSL; Mars; Large Eddy Simulations; LES; Reynolds-Averaged Navier–Stokes equations; RANS;

    Sammanfattning : Hot wire anemometers have been used in several wind velocity sensors deployed in Mars. They are based in keeping the temperature of a surface at a constant value, above the ambient. This is done by means of a heater controlled with an electronic system. LÄS MER

  3. 2. Developing a measurement system of fluid velocities in rotating bed reactors

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Måns Sterner Boström; [2016]
    Nyckelord :fluid measurement; hot-wire constant temperature anemometer; CTA; constant temperature anemometer;

    Sammanfattning : SpinChem AB's rotating bed reactor (RBR) is a small cylindrical centrifuge that allowsfor eective convective reactions between chemical substances. The aim of my master'sdissertation was to develop a measurement system that could estimate the uid velocity insidethe RBR. LÄS MER

  4. 3. Quality and representability of mobile measurements for local climatological research

    Magister-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Christine Achberger; [1996]
    Nyckelord :geography; physical geography; mobile measurements; local climatological research; Earth and Environmental Sciences;

    Sammanfattning : Temperature recordings from a moving vehicle are frequently used in microclimatological research. This work aims at investigating three aspects of the quality and the representability of mobile-recorded temperature data: the displacement of air near the car's front; the inertia of the sensors which hinders the accurate recording of fast fluctuations, and how good temperature profiles obtained above a road correspond to temperature profiles of areas adjacent to the road.
