  1. 1. Thermo-electric temperature measurements in friction stir welding Towards feedback control of temperature

    University dissertation from Trollhättan : University West

    Author : Ana Magalhães; Högskolan Väst.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FSW; Robotic; Temperature; TWT; Plunge; Control; Production Technology; Produktionsteknik;

    Abstract : Friction Stir Welding has seen a fast uptake in many industry segments. Mechanical properties superior to fusion welding, the ability to weld "unweldable" aluminium alloys and low distortion are often described as the main reasons for the fast industrial implementation of FSW. Most existing applications consist of long straight welding joints. READ MORE

  2. 2. Determination of the thermal conductivity of the insulation in district heating mains : Field measurements

    University dissertation from Göteborg : Chalmers tekniska högskola, Institutionen för byggnadsfysik

    Author : Karin Margaretha Borgström; Högskolan i Halmstad.; [1994]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating main; field measurements; thermal conductivity; measuring method; heat flow measurement; heat flux sensor; TECHNOLOGY Engineering physics Material physics with surface physics; TEKNIKVETENSKAP Teknisk fysik Materialfysik med ytfysik;

    Abstract : This thesis concerns the development of a measurement method for determination in the field of the thermal conductivity of the insulation in buried district heating mains. The thermal conductivity of the insulation is calculated from the measured value of the radial heat flow through the heating main, the measured temperature difference across the insulation, and the dimensions of the heating main.

  3. 3. Compartment Fire Temperature Calculations and Measurements

    University dissertation from Luleå University of Technology

    Author : Alexandra Byström; Luleå tekniska universitet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compartment fire temperature; heat transfer; FEM; calculation of temperature; temperature measurement; fire scenario; validation; flashover; Stålbyggnad; Steel Structures;

    Abstract : This thesis is devoted to heat transfer and fire dynamics in enclosures. It consists of a main part which summarizes and discusses the theory of heat transfer, conservation of energy, fire dynamics and specific fire scenarios that have been studied. READ MORE

  4. 4. Mesospheric measurements using microwave spectroscopy

    University dissertation from Luleå University of Technology

    Author : Ole Martin Christensen; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; water vapour; microwave spectroscopy; polar mesospheric clouds; remote sensing; mesosphere; retrieval; carbon monoxide; temperature; ozone; noctilucent clouds;

    Abstract : The mesosphere is an altitude region of the atmosphere, covering altitudes between about 50 km to 100 km. Improved understanding of this area of the atmosphere offers possibilities of increasing the accuracy of weather forecast and climate models. READ MORE

  5. 5. Heat Flow in Building Components, Experiment and Analysis

    University dissertation from Department of Building Science, Lund Institute of Technology

    Author : Petter Wallentén; Lunds universitet.; Lund University.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radiation exchange; longwave; shortwave; transient; frequency analysis; finite difference; measurements; wall; window; heat transfer coefficient; convective; full scale; natural climate; in situ; counter flow insulation; heat transfer; dynamic insulation; temperature; building; solar radiation; window model; Building construction; Byggnadsteknik;

    Abstract : Three building components exposed to natural climate were studied: a dynamic insulation in the ceiling of a house, an outer wall and one window in the same wall. The term dynamic insulation implies that part of the inlet or exhaust air passes through the insulation of a house. READ MORE
