  2. 21. Laser metal fusion and deposition using wire feedstock : Process modelling and CFD simulation

    Author : Seyyed Mohammad Ali Noori Rahim Abadi; Isabelle Choquet; Fredrik Sikström; Norbert Enzinger; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Directed Energy Deposition with wire; Beam shaping; Absorptivity; Conduction-mode; Free surface deformation; Computational Fluid Dynamics; OpenFOAM.; Riktad energideponering med svetstråd; Stråformning; Absorption; Svetsning; Ytdeformation; Beräkningsströmningsdynamik; OpenFOAM.; Production Technology; Produktionsteknik;

    Abstract : Laser metal fusion is widely used in production technology to manufacture parts, as in welding, cladding, and additive manufacturing. In this study, conduction mode laser metal fusion is applied without and with metal deposition from a wire feedstock. READ MORE

  4. 22. Influence of Bridge Structures on the Electron Transfer in Donor-Acceptor Systems

    Author : Mikael Winters; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular wire; electron transfer; porphyrin; conjugated oligomer;

    Abstract : In this Thesis, porphyrin-based donor-acceptor systems have been used to study photoinduced electron transfer processes. Principally, two different sets of systems have been investigated. READ MORE

  5. 23. Experimental study of the rotating-disk boundary-layer flow

    Author : Shintaro Imayama; Henrik Alfredsson; Rebecca Lingwood; Benoît Pier; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; boundary layer; rotating disk; laminar-turbulent transition; convective instability; absolute instability; secondary instability; crossflow instability; hot-wire anemometry.;

    Abstract : Rotating-disk flow has been investigated not only as a simple model of cross flow instability to compare with swept-wing flow but also for industrial flow applications with rotating configurations. However the exact nature of laminar-turbulent transi- tion on the rotating-disk flow is still major problem and further research is required for it to be fully understood, in particular, the laminar-turbulent transition process with absolute instability.

  6. 24. A Study on the Thermal State of Steelmaking Ladles

    Author : Björn Glaser; Du Sichen; Petrus Christiaan Pistorius; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steelmaking ladle; refractory; thermal conductivity; transient hot wire method; slag; peheating;

    Abstract : In the present thesis a study on the thermal state of steelmaking ladles was undertaken. The transient hot wire method was verified for thermal conductivity measurements on metallurgical slags and applied to ladle slag measurements. Temperature measurements on ladles in an industrial environment were carried out. READ MORE

  7. 25. On Distributed Control-by-Wire Systems for Critical Applications

    Author : Roger Johansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; time-triggered communication; fault-tolerance; distributed systems; dependable systems; inherent redundancy; control-by-wire;

    Abstract : The implementation of closed loop control systems is an important field for the exploitation of embedded real-time computer systems. One can find a particularly interesting class of closed loop control applications within vehicle dynamics control. READ MORE
