  1. 1. A physical modeling study of top blowing with focus on the penetration region

    Författare :Annie Nordquist; Per Jönsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; physical modelling; top blown converters; lances; blowing; penetration; swirl; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : This thesis work aimed at increasing the knowledge regarding phenomena occurring when gas is injected using a top-blown lance on to a bath. All results are based on physical modeling studies carried out both using low and high gas flow rates and nozzle diameters ranging from 0.8 mm to 3.0 mm. LÄS MER

  5. 4. Blowing Agents in Rigid Polyurethane Foam - Analytical Studies - Technical and Environmental Aspects

    Författare :Magdalena Svanström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; insulation; ageing; district heating pipes; cyclopentane; CFC-11; carbon dioxide; diffusion; blowing agents; polyurethane foam;

    Sammanfattning : Rigid polyurethane foam is used in many different applications because of its high insulating capacity. CFC-11 has been the predominant blowing agent due to its advantageous properties, especially its low thermal conductivity. LÄS MER

  7. 5. Investigations of Flow Conditions in an Automotive Wind Tunnel

    Författare :Emil Ljungskog; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind tunnel; Ground simulation; Tangential blowing; CFD simulations; Slotted walls;

    Sammanfattning : As vehicle manufacturers seek to shorten the development time of new models, wind tunnel testing of prototype vehicles needs to be partially replaced by virtual simulations. However, this requires thorough validation of the virtual methods, which is done by comparison to wind tunnel tests. LÄS MER
