  3. 2. Thermoelectric transport and thermometry of quantum dots

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Författare :Martin Josefsson; [2015]
    Nyckelord :thermoelectricity; quantum dot; QD; quantum transport; solid state physics; Technology and Engineering; Physics and Astronomy;

    Sammanfattning : Thermoelectricity is the physical principle of converting heat energy directly into electrical energy. Devices based on this principle so far fall short on efficiency but future thermoelectric devices based on QDs can have very high efficiency. Before QDs can be used in actual devices their behavior must the studied to a further extent. LÄS MER

  4. 3. Waste heat recovery system with new thermoelectric materials

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Fredrik Borgström; Jonas Coyet; [2015]
    Nyckelord :;

    Sammanfattning : Increasing fuel prices, higher demands on "greener" transports and tougher international emission regulations puts requirements on companies in the automotive industry in improving their vehicle fuel efficiency. On a typical heavy duty Scania truck around 30% of the total fuel energy is wasted through the exhaust system in terms of heat dissipated to the environment. LÄS MER

  5. 4. A Theoretical Investigation of Thermoelectrics in Nanowires Embedded With a Quantum Dot Superlattice

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Författare :John Lovén; [2015]
    Nyckelord :Thermoelectricity; nanotechnology; nanowire; quantum dot; superlattice.; Technology and Engineering;

    Sammanfattning : Thermoelectric elements have long been anticipated to challenge conventional solutions for converting heat to electricity. However, the revolution has been stalled due to the inability to reach efficiencies comparable to their conventional counterparts, while retaining a high output power. LÄS MER

  7. 5. Mild Hybrid System in Combination with Waste Heat Recovery for Commercial Vehicles

    Master-uppsats, Maskinkonstruktion; Tekniska högskolan

    Författare :Mohsen Namakian; [2013]
    Nyckelord :Waste heat recovery; hybrid electric vehicle; thermoelectricity; thermoelectric generators; fuel economy; mild-hybrid; full-hybrid;

    Sammanfattning : Performance of two different waste heat recovery systems (one based on Rankine cycle and the other one using thermoelectricity) combined with non-hybrid, mild-hybrid and full hybrid systems are investigated. The vehicle under investigation was a 440hp Scania truck, loaded by 40 tons. LÄS MER
