  2. 6. Modelling of Electric Arc Welding : arc-electrode coupling

    Author : Alireza Javidi Shirvan; Isabelle Choquet; Håkan Nilsson; Alexei Heintz; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric welding; arc welding simulation; electrode; plasma; cathode layer; sheath; arc discharge; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Arc welding still requires deeper process understanding and more accurateprediction of the heat transferred to the base metal. This can be provided by CFD modelling.Most works done to model arc discharge using CFD consider the arc corealone. READ MORE

  4. 7. Moral (de)coupling : moral disengagement and supply chain management

    Author : David Eriksson; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; abduction; CSR; Corporate Social Responsibility; critical realism; ethics; moral decoupling point; moral disengagement; moral responsibility; supply chain management; sustainability; systematic combining; textile management; TBL; Triple bottom line; Textiles and Fashion General ; Textil och mode generell ;

    Abstract : This research aims to fill an important gap in focusing on why individuals are able to take part in and/or support activities that have effects on economic, environmental, and social dimensions that are not consistent with their sense of right and wrong. The research focuses on the relationship between supply chain management and moral disengagement, and how this relation affects social responsibility. READ MORE

  5. 8. Vibration transmission in lightweight buildings : Numerical prediction models

    Author : Ola Flodén; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration transmission; structure-borne sound; wood buildings; numerical modelling; finite element method; structure-acoustic coupling; model validation; model calibration; dynamic substructuring; model order reduction;

    Abstract : Ljud från grannar är ett återkommande problem för boende i flerfamiljshus. Problemen är generellt mer omfattande för de som bor i flervåningshus byggda i trä, en byggnadstyp som blir allt vanligare i Sverige. Många av de boende i trähus upplever även att störande vibrationer är vanligt förekommande i trähus. READ MORE

  6. 9. A Model for Simulation of Fiber Suspension Flows

    Author : David Hammarström; KTH; []
    Keywords : rheology; fiber; suspension; CFD; model; wall; slip; turbulence;

    Abstract : The fiber suspensions in the production line from wood topaper are subjected to many types of chemical and mechanicalprocesses, in which the flow of the suspension is of vitalimportance. The flow of the suspension determines the degree ofuniformity of the fibers through the processing, which inreturn affects the properties of the fiber suspension. READ MORE

  7. 10. Numerical simulation and analysis of multi-scale cavitating flows using a hybrid mixture-bubble model

    Author : Ebrahim Ghahramani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Homogeneous mixture model; Lagrangian bubble model; CFD; Cavitation; OpenFOAM; Multiphase flow; Hybrid model; Multi-scale;

    Abstract : The aim of this research is to model and analyse multi-scale cavitating flows with a certain emphasis on small sub-grid vapour structures. Cavitating flows include vapour structures with different length scales, from micro-bubbles to large cavities. READ MORE
