  4. 7. Modelling of Bingham Suspensional Flow : Influence of Viscosity and Particle Properties Applicable to Cementitious Materials

    Author : Annika Gram; Björn Lagerblad; Ulrich Diederichs; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-Compacting Concrete; SCC; Fresh concrete flow; Numerical simulation; Viscosity; Open channel flow;

    Abstract : Simulation of fresh concrete flow has spurged with the advent of Self-Compacting Concrete, SCC. The fresh concrete rheology must be compatible with the reinforced formwork geometry to ensure complete and reliable form filling with smooth concrete surfaces. READ MORE

  5. 8. Learning flow functions : architectures, universal approximation and applications to spiking systems

    Author : Miguel Aguiar; Karl H. Johansson; João Sousa; Maarten Schoukens; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Learning flow functions of continuous-time control systems is considered in this thesis. The flow function is the operator mapping initial states and control inputs to the state trajectories, and the problem is to find a suitable neural network architecture to learn this infinite-dimensional operator from measurements of state trajectories.

  6. 9. Experimental and numerical investigations of hydrodynamic focusing of colloidal dispersions

    Author : V. Krishne Gowda; Fredrik Lundell; Daniel Söderberg; Lynn Walker; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microfluidics; flow focusing; colloidal fiber dispersion; effective interfacial tension; microflow morphology; nanoparticle orientation; Mikrofluidik; flödesfokusering; kolloidala dispersioner; effektiv ytspänning; mikroflödesmorfologi; orientering av nanopartiklar; Teknisk mekanik; Engineering Mechanics;

    Abstract : Dispersed non-spherical particles are the fundamental constituent of many complex fluids. Such fluids are studied both for their industrial and scientific importance, and for their peculiar functional properties (mechanical, optical, thermal, fluidic). READ MORE

  7. 10. Numerical simulations of flow discharge and behaviours in spillways

    Author : Shicheng Li; Anders Ansell; James Yang; Sébastien Erpicum; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spillway; step geometry; discharge prediction; flow behaviour; machine learning; computational fluid dynamics; Utskov; steggeometri; avbördningsuppskattning; flödesbeteende strömningsegenskap; maskininlärning; flödesdynamisk beräkningsanalys numerisk simulering; Betongbyggnad; Concrete Structures;

    Abstract : A spillway is an important component of a dam and serves as a flood release structure. It achieves controlled discharge of water and protects the dam from overtopping. The majority of the hydropower dams were built before the 1980s, and many spillways are undersized in light of the present design flood guidelines. READ MORE
