  1. 1. Modeling stormwater transport through unsaturated green roof substrates

    Författare :Kaj Pettersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modeling; Lattice Boltzmann; porous media; CFD; saturation; multiphase; Green roofs;

    Sammanfattning : In recent decades there has been an increase in research regarding green roofs and similar technologies. This increased interest is driven by the requirements of urban development and its effects both on humans and the environment. LÄS MER

  3. 2. Analysis of the Base Wake on Passenger Vehicles

    Författare :Lennert Sterken; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pressure measurements; External aerodynamics; Wind tunnel; Wake; Local drag; CFD;

    Sammanfattning : Car manufacturers are presented by a continuous increase in fuel prices and by ever more strict legislations regarding CO2-emissions. Decreasing the driving resistance and hence the fuel consumption of their vehicles helps to improvetheir market share. LÄS MER

  4. 3. Prestressed hybrids of AAC and HPC : The BCE (Block Composed Element) building system. A conceptual study

    Författare :Hamid Bagheri; Bo Göran Hellers; Jonas Holmgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture and architectural conservation and restoration; Arkitektur och bebyggelsevård;

    Sammanfattning : There is an important potential for a development of a building system, if the present AACblock plants are completed with high performance concrete and pre-stressing technique. This can be done as a continuation of a present AAC production or in a site factory. Hybrid cooperation between AAC and concrete is not a new technology. LÄS MER

  5. 4. Industrial Fibre Concrete Floors : Experiences and Tests on Pile-Supported Slab

    Författare :Jerry Hedebratt; Johan Silfwerbrand; Terje Kanstad; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Pile supported floor slabs have often been designed solely in ultimate limit state ULS and then foremost with uniformly distributed loadings UDL. The investigation of serviceability limit state SLS has been of simpler nature, even according to the governing codes of practice. LÄS MER
