  1. 21. Mechanism of zeolite activity in biogas co-digestion

    University essay from Institutionen för fysik, kemi och biologi

    Author : Anna Hansson; [2011]
    Keywords : Anaerobic digestion; methane; zeolites; clinoptilolite; slaughterhouse waste;

    Abstract : Biogas is a source of renewable energy and is produced at anaerobic conditions. The gas consists mainly of methane (55-70 %) and carbon dioxide (30-45 %). Biogas can be used as vehicle fuel after the gas has been upgraded to a methane content of approximately 97 %. There are several companies in Sweden producing biogas. READ MORE

    Abstract : Quality of the output power delivered from the utilities has become a major concern of the modern industries for the last decade. These power quality associated problems are voltage sag, surge, flicker, voltage imbalance, interruptions and harmonic problems. READ MORE

  4. 23. Surge Modeling and Control of Automotive Turbochargers

    University essay from Institutionen för systemteknik

    Author : Oskar Leufvén; Johan Bergström; [2007]
    Keywords : Compressor; Mean Value Engine Modeling; Surge control; Surge line; Surge valve;

    Abstract : Mean Value Engine Modeling (MVEM) is used to make engine control development less expensive. With more and more cars equipped with turbocharged engines good turbo MVEM models are needed. A turbocharger consists of two major parts: turbine and compressor. READ MORE

  5. 24. Bypass Modeling and Surge Control for turbocharged SI engines

    University essay from Institutionen för systemteknik

    Author : Eric Wiklund; Claes Forssman; [2005]
    Keywords : Mean Value Engine Modeling; Bypass valve; Surge control; Wastegate; TOMOC;

    Abstract : Since measurements in engine test cells are closely coupled with high costs it is of interest to use physically interpretable engine models instead of engine maps. Such engine models can also be used to do off-line tests of how new or altered components affects engine performance. READ MORE
