    Sammanfattning : Using woody biomass as a resource for production of biofuel, heat and power through gasification has been studied for years. In order to reduce the cost of operating and to design the full-scale gasification plant developing a general model to be applicable for different ranges of input data with acceptable level of accuracy, is needed.

  3. 13. Efficient modeling and control of crushing processes in minerals processing

    Författare :Marcus Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HPGR; Comminution; Jaw crusher; Process control; Modeling; Dynamic modeling; Minerals processing;

    Sammanfattning : Modeling and simulation is a tool to explore and increase the understanding of a phenomenon. This thesis focuses on developing models of crushers and equipment used in the mining industry. Specifically, the focus is on a branch of modeling called time dynamic modeling which is a model that gives an output as a function of time. LÄS MER

  4. 14. Metal film growth on weakly-interacting substrates : Multiscale modeling

    Sammanfattning : Thin films are nanoscale layers of material used to functionalize surfaces or to serve as building blocks in more complex devices. In recent years, thin metal films have become vital for modern devices within, e.g. LÄS MER

  5. 15. Modeling and Simulation of a Multi Phase Semi-batch Reactor

    Författare :Anna Nyström; Göteborgs universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; semi-batch reactor; modeling; simulation; optimization; simulation;

    Sammanfattning : The operation of an industrial semi-batch reactor is modeled and the flow of one reactant is investigated. In the reactor a strongly exothermic polymerization reaction takes place followed by a slightly exothermic reaction, and the objective is to minimize the duration of the operation of the process.
