  1. 36. A Generic Model for Simulation of the Energy Performance of Ships - from Early Design to Operational Conditions

    Författare :Fabian Tillig; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; uncertainty analysis; ship design; ship operation; energy systems modelling; ship energy efficiency; fuel consumption;

    Sammanfattning : Forecasts show a doubling of the world’s transportation needs until 2050. Shipping today accounts for 90% of all freight transport. Simultaneously, shipping must become cleaner and more energy-efficient to meet the target to more than halve 2005 greenhouse gas emissions by 2050. LÄS MER

  3. 37. Water powered percussive rock drilling : process analysis, modelling and numerical simulation

    Författare :Göran Tuomas; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : This thesis is devoted to problems, processes and systems related to the recently developed water powered percussive rock drilling method. The technology, which uses ordinary water to drive down-the-hole hammers, has been used to produce more than 6 million meters of blast holes within the mining industry. LÄS MER

  4. 38. National Energy System Modelling of Industry : Optimising the Transition Towards Carbon Neutrality

    Författare :Erik Sandberg; Anna Krook-Riekkola; Andrea Toffolo; Åsa Lindman; Peter Lund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : Industry is a major user of energy and emitter of fossil CO2. At the same time, Sweden targets net-zero greenhouse gas emissions by 2045. Current policies to reduce greenhouse gas emissions and mitigate climate change, and the transition of the energy system it requires, will present major challenges for industry. LÄS MER

  5. 39. The impact of an Electrification of Road Transportation on the Electricity system in Scandinavia

    Författare :Maria Taljegård; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric road systems; energy consumption; peak power; electric car; variation management; energy system modelling;

    Sammanfattning : The transport sector needs to reduce CO2 emissions by replacing fossil fuels with low-carbon options. An electrification of the road transport sector through electric vehicles (EVs) with static charging; electric road systems (ERS); and using electricity to produce a fuel, are all suggested as possible options.

  7. 40. Digester modelling for diagnostics and control

    Författare :Johan Jansson; Erik Dahlquist; Thore Berntsson; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pulp production; diagnostics; simulation; control; Cellulose and paper engineering; Cellulosa- och pappersteknik; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : This thesis will show the possibility for the development and use of an on-line model for application to continuous digesters for pulp production. The model is developed by using a program called Dymola (Dynamic Modeling Laboratory). What makes the Dymola software so well suited is that the program solves equations simultaneously. LÄS MER
