  2. 1. Compartment Fire Temperature Calculations and Measurements

    Author : Alexandra Byström; Ulf Wickström; Sven Thelandersson; Luleå tekniska universitet; []
    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. 2. Temperature and heat losses simulation in core and winding of a power transformer

    Author : Kourosh Mousavi Takami; Mahmoudi Jafar; Lennart Harnefors; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Power Transformer; Losses; Simulation; Temperature; Calculation; Electric power engineering; Elkraftteknik; elektronik; Electronics;

    Abstract : Simulering av temperatur och värmeförluster i kärna och lindning för en högspänningstransformator “... Ett ljus som lyser dubbelt så starkt, varar hälften så länge …”, i analogi med ljuset så kan transformatorer köras med överlast inom vissa gränser, men med följden att livslängden blir kortare.

  5. 3. Modeling and Optimization of Reversed-Phase Chromatography : Effects of Modulators and Temperature

    Author : Karolina Arkell; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reversed-phase chromatography; Hydrophobic interaction chromatography; Mechanistic modeling; INSULIN; KCl; Ethanol; Temperature; Multi-objective optimization; Constraint; Solubility;

    Abstract : Many widespread diseases, such as diabetes, various types of cancer, and aggressive versions of influenza, are treated or prevented with biopharmaceuticals. Biopharmaceuticals are drugs that are based on proteins, peptides, antibodies, attenuated viruses (vaccines), and other biomolecules that are synthesized predominately in bacteria, yeast, and mammalian cells.

  6. 4. Control of weldability : Research leading to the development of two new quenched and tempered tool steels

    Author : Per Hansson; Hannerz Nils Erik; Torsten Eriksson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : The understanding of the hardenability is important in steel development with respect to weldability of steels as well as to the design of quenched and tempered steels.The common way to judge if steel is suitability to welding is the use of a carbon equivalent, which reflects the alloy content to the hardenability of the heat affected zone (HAZ).

  7. 5. Evaluation of the Performances of Electrically Heated Clothing

    Author : Faming Wang; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrically heated vest EHV ; heating efficiency; cold weather clothing; air velocity; clothing combination; thermal resistance; air temperature;

    Abstract : Cold weather garments are necessary for people who are exposed to cold environments (below -5 °C). The weight and bulkiness of such a cold weather clothing ensemble may limit human activity and reduce the productivity. In order to solve these problems, a slim garment with a built-in heating element could be useful. READ MORE
