  1. 21. Modelling and Simulation of Turbulent Gas-Solid Flows applied to Fluidization

    Författare :Eric Peirano; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eulerian models; fluidization; two-fluid model; two-phase flow; granular flow theory; turbulence; fluidized beds; gas-solid flows;

    Sammanfattning : Modelling of gas-solid suspensions has been studied with emphasis on suitable closure laws. A study of characteristic time scales and energy dissipation mechanisms is made for the case of a simple shear flow. Applications of the modelling are presented in the form of simulation and validation of experiments in fluidized beds. LÄS MER

  2. 22. Optimizing Networked Systems and Inverse Optimal Control

    Författare :Han Zhang; Xiaoming Hu; Elias Jarlebring; Yiguang Hong; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Networked systems; energy optimal consensus control; semi-definite programming; distributed optimization; inverse optimal control; Mathematics; Matematik;

    Sammanfattning : This thesis is concerned with the problems of optimizing networked systems, including designing a distributed energy optimal consensus controller for homogeneous networked linear systems, maximizing the algebraic connectivity of a network by projected saddle point dynamics. In addition, the inverse optimal control problems for discrete-time finite time-horizon Linear Quadratic Regulators (LQRs) are considered. LÄS MER
