  1. 1. Data preparation, hydrodynamic and contaminant transport shallow-water simulations of Lake Victoria

    Author : Seema Paul; Vladimir Cvetkovic; Jesper Oppelstrup; Roger Thunvik; Felix Mtalo; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake bathymetry model; Steady-state analysis; Numerical model validation; Lake water balance; Correlation and seasonal variations; Solute transport; Vattendjupskarta; Validering av numerisk modell; Vattenbalans; Korrelationer och säsongs-variation; Transport av lösliga ämnen; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : This study explores shallow lake numerical hydrodynamic processes that support model development and validation, extreme events and effects of water circulation in Lake Victoria. Lake Victoria is the second largest freshwater lake in the world, and the largest in East Africa. READ MORE

  2. 2. Prediction and experimental validation of dynamic soil-structure interaction of an end-bearing pile foundation in soft clay

    Author : Freddie Theland; Jean-Marc Battini; Amir Kaynia; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic soil-structure interaction; Pile group; End-bearing piles; Dynamic impedance; Environmental vibration; Experimental validation; Dynamisk jord-struktur-interaktion; Pålgrupp; Spetsbärande pålar; Dynamisk impedans; Omgivningsvibrationer; Experimentell validering; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Abstract : In the built environment, human activities such as railway and road traffic, constructionworks or industrial manufacturing can give rise to ground borne vibrations. Such vibrations become a concern in urban areas as they can cause human discomfort or disruption of vibration sensitive equipment in buildings. READ MORE

  3. 3. Optimal Pin Fin Heat Exchanger Surface

    Author : Hamid Nabati; Jafar Mahmoudi; Mohsen Assadi; Mälardalens högskola; []
    Keywords : Pin Fin; CFD; Numerical Simulation; Power Transformer; TECHNOLOGY; TEKNIKVETENSKAP; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : This research presents the results of numerical study of heat transfer and pressure drop in a heat exchanger that is designed with different shape pin fins. The heat exchanger used for this research consists of a rectangular duct fitted with different shape pin fins, and is heated from the lower plate. READ MORE

  4. 4. On synchronization of heavy truck transmissions

    Author : Daniel Häggström; Ulf Sellgren; Stefan Björklund; Anders Hedman; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synchronization; synchronizers; gear shift; gearbox; synkronisering; växling; växellåda; Machine Design; Maskinkonstruktion;

    Abstract : Gear shifts are becoming more and more important as engines are adapted to low speed high torque working conditions. Synchronizers are key components for successful gear shifts. To adapt the synchronizers to new working conditions due to adaptations to new engines, improved development tools are needed. READ MORE
