  1. 1. 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.

  2. 2. 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

  3. 3. Visualization of Air Flow, Temperature and Concentration Indoors Whole-field measuring methods and CFD

    University dissertation from Stockholm : KTH

    Author : Mathias Cehlin; Högskolan i Gävle.; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Whole-field; CFD; Visualization; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik;

    Abstract : The thermal indoor climate is a complicated combination of a number of physical variables, all of which strongly affect people’s well-being. The indoor climate not only heavily affects people’s health and life quality, but also their productivity and ability to work efficiently. READ MORE

  4. 4. Spatial variations of the urban climate and its influence on thermal comfort and behaviour

    University dissertation from Göteborg : Göteborg University

    Author : Fredrik Lindberg; Göteborgs universitet.; Gothenburg University.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sky view factor; air temperature; surface temperature; GIS; raster modelling; mean radiant temperature; globe temperature; the SOLWIEG-model; human behaviour; outdoor activity;

    Abstract : The increased number of people living in urban areas emphasises the need for an improved understanding of how the urban climate affects human activity and behaviour. The spatial and temporal variation of climate within cities is an important factor in people’s health and well-being. READ MORE

  5. 5. Acclimation of plants to combinations of abiotic factors connecting the lab to the field

    University dissertation from Umeå : Umeå University

    Author : Zsofia Réka Stangl; Umeå universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nitrogen; carbon dioxide; temperature; thermal acclimation; mycorrhiza; boreal forest; climate change; C:N balance; allocation; respiration; photosynthesis; terrestrial biosphere model;

    Abstract : Increasing atmospheric CO2 and other greenhouse gasses coupled to the accelerated rate of global warming puts plants and ecosystems under the strain of a rapidly changing abiotic environment. Understanding the impacts of changing global climate is a strong focus of plant science and the establishment of more resilient crop variants is an important goal for breeding programs. READ MORE
