  1. 6. Model based approach to resistive wall magnetohydrodynamic instability control : Experimental modeling and optimal control for the reversed-field pinch

    Författare :Agung Chris Setiadi; Per Brunsell; Lorenzo Frassinetti; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; magnetohydrodynamic; model based control; reversed-field pinch; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The primary objective of fusion research is to realize a thermonuclear fusion power plant. The main method to confine the hot plasma is by using a magnetic field. The reversed-field pinch is a type of magnetic confinement device which suffers from variety of magnetohy- drodynamic (MHD) instabilities. LÄS MER

  4. 8. Resistive Wall Mode Stability and Control in the Reversed Field Pinch

    Författare :Dmitriy Yadikin; Per Brunsell; Mikhail Gryaznevich; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resistive wall modes; RWM; active control; feedback; MHD modes; Reversed-Field pinch; RFP; intelligent shell; mode control; Electrophysics; Elektrofysik;

    Sammanfattning : Control of MHD instabilities using a conducting wall together with external magnetic fields is an important route to improved performance and reliability in fusion devices. Active control of MHD modes is of interest for both the Advanced Tokamak and the Reversed Field Pinch (RFP) configurations. LÄS MER

  5. 9. Energy Export Opportunities from Kraft Pulp and Paper Mills and Resulting Reductions in Global CO2 Emissions

    Författare :Erik Marcus Kristian Axelsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy export; Heat integration; Energy savings; Kraft pulp and paper mill; Global CO2 emissions;

    Sammanfattning : With increasing energy prices and increasing demand for CO2-lean energy sources, energy savings in the pulp and paper industry become ever more relevant. Significant energy savings in kraft mills can be made by e.g. improved heat integration and installation of an energy-efficient evaporation plant. LÄS MER

  7. 10. Optimum Design of Heat Exchanger Networks in Retrofit Situations

    Författare :Annika Carlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimum design; pressure drop; process integration; pinch thechnology; heat transfer coefficients; heat exchanger networks; retrofit;

    Sammanfattning : Today, the most important activity in heat exchanger network synthesis is the retrofitting, rather than grass-root design, of networks. There is a vast potential for energy improvement in many processes by increasing the level of internal heat exchange. LÄS MER
