  1. 1. Nature-inspired passive flow control using various coatings and appendages

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Ugis Lacis; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow control; passive appendage; surface coating; pressure drag; friction drag; Flödeskontroll; passiva bihang; ytbeläggning; tryckmotstånd; friktionsmotstånd;

    Sammanfattning : There is a wide variety of tails, fins, scales, riblets and surface coatings, which are used by motile animals in nature. Since organisms currently living on earth have gone through millions of years of evolution, one can expect that their design is optimal for their tasks, including locomotion. LÄS MER

  2. 2. Models of porous, elastic and rigid materials in moving fluids

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Ugis Lacis; KTH.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid-structure-interaction; flow control; passive appendages; homogenization; poroelastic coatings; separated flows; surface-fluid interface; fluid-struktur-interaktion; flödeskontroll; passiva utväxter; homogenisering; ytbeläggning; separerade strömning; ytbeläggning-strömning gränssnitt; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Tails, fins, scales, and surface coatings are used by organisms for various tasks, including locomotion. Since millions of years of evolution have passed, we expect that the design of surface structures is optimal for the tasks of the organism. These structures serve as an inspiration in this thesis to identify new mechanisms for flow control. LÄS MER
