  2. 2. Short term water heat storage an experimental and numerical investigation of phenomena that affect the degree of thermal stratification

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Roger Hermansson; Luleå tekniska universitet.; [1993]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : Thermal stratification was studied by measurements of the temperature and velocity fields in water heat storage's and by numerical simulations. The work includes experimental investigations in three model heat storage's of different size and comparisons to numerical simulations for two of the storages. LÄS MER

  3. 3. Studies of the flow pattern in short term hot water storages

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Pascal Veber; [1998]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : This thesis relates to the study of thermally stratified hot water storages used in district heating systems and is an extension of the doctoral theses of Jan Dahl and Roger Hermansson. The thermal performance of a stratified water storage is reduced by different phenomena such as heat transfer to the surroundings and mixing between hot and cold water during the charging of the tank.
