  6. 4. Process Integration of Industrial Heat Pumps in Grass-Root and Retrofit Situations

    Author : Erik Wallin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process integration; pinch technology; retrofit; industrial heat pumps; grass-root;

    Abstract : In several works, methods for process integration of heat pumps (HPs) have been developed, which in turn have been used for case studies in different industrial types. HP integration has thus proven to be a promising technique for utility savings and attractive payback periods. READ MORE

  7. 5. Nonaxisymmetric experimental modal analysis and control of resistive wall MHD in RFPs : System identification and feedback control for the reversed-field pinch

    Author : K Erik J Olofsson; Per Brunsell; Marco Ariola; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic confinement fusion; Reversed-field pinch; System identification; Magnetohydrodynamics; Modal analysis; Automatic control; Resistive wall modes;

    Abstract : The reversed-field pinch (RFP) is a device for magnetic confinement of fusion plasmas. The main objective of fusion plasma research is to realise cost-effective thermonuclear fusion power plants. The RFP is highly unstable as can be explained by the theory of magnetohydrodynamics (MHD). READ MORE
