    Sammanfattning : Rapid heat transfer methods such as jet impingement and infrared radiation can be used to speed up thermal processing in the food industry. The heating rate affects important food characteristics, such as colour. LÄS MER

  3. 3. Quantum Correlations and Temperature Fluctuations in Nanoscale Systems

    Författare :Fredrik Brange; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum transport; electronic entanglement; nanoscale thermodynamics; quantum calorimetry; Fysicumarkivet A:2019:Brange;

    Sammanfattning : This thesis addresses two different topics related to the physics of nanoscale systems. The first topic concerns quantum correlations and entanglement between electrons in solid-state systems, with a focus on how to generate electronic orbital entanglement on a sub-decoherence time scale and how to achieve experimentally more feasible entanglement detection schemes.

  5. 5. Thermal response tests : influence of convective flow in groundwater filled borehole heat exchanger

    Författare :Anna-Maria Gustafsson; Jeffrey D. Spitler; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering; VA-teknik; Urban Water Engineering;

    Sammanfattning : The main objective of this doctorial thesis was to investigate how thermally induced movements in the groundwater (natural convective flow) may influence the heat transport in borehole and surrounding bedrock in a groundwater filled borehole heat exchanger system. The purpose was also to determine if thermal response tests could be used to detect the convective influence and the effect on evaluated heat transfer parameters, effective bedrock thermal conductivity and borehole thermal resistance.
