  1. 1. Flow over rough surfaces, and conjugate heat transfer, in engineering applications

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Bercelay Niebles Atencio; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Skin-Friction Drag; Naphthalene Sublimation Tecnhique; correlation; RANS; Rotating Disk; stator channel; CFD; convective heat transfer; Antifouling paint; electric generator; Impinging Jet; Ship Hull; Roughness Function;

    Abstract : This thesis focuses on two important topics in the field of fluid mechanics and heat transfer that were treated separately. On the one hand, the flow over rough surfaces, which is not yet completely understood, despite of the fact that it has an important implication in many engineering applications, especially in the naval industry for ships and boats because the friction drag caused by fouling, antifouling coatings and roughness in general impacts the fuel consumption and toxic emissions to the atmosphere.

  2. 2. Low biocide emission antifouling based on a novel route of barnacle intoxication

    University dissertation from Göteborg : University of Gothenburg

    Author : Emiliano Pinori; Göteborgs universitet.; Gothenburg University.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antifouling; Barnacles; ivermectin; low biocide emission; marine fouling; marine paint; ISO 15181; ToF-SIMS;

    Abstract : Marine biofouling can be defined as the colonization of man-made surfaces in seawater by microscopic and macroscopic organisms. This phenomenon can result in great loss of function and effectiveness both for cruising ships and for static constructions. READ MORE

  3. 3. Corrosion-induced release of zinc and copper in marine environments

    University dissertation from Stockholm : KTH

    Author : Jan Sandberg; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; copper; zinc; marine environment; runoff rate; atmospheric corrosion; chloride deposition; anti-fouling paints; chemical speciation; bioavailability; cupric ions; TECHNOLOGY Materials science Other materials science; TEKNIKVETENSKAP Teknisk materialvetenskap Övrig teknisk materialvetenskap;

    Abstract : This licentiate study was initiated by copper, zinc and galvanized steel producers in Europe, who felt a need to assess runoff rates of copper and zinc from the pure metals and commercial products at marine exposure conditions. Their motive was the increasing concern in various European countries and the on-going risk assessments of copper and zinc within the European commission. READ MORE

  4. 4. Occurrence and environmental risk assessment of antifouling paint biocides from leisure boats

    University dissertation from Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Author : Maria Lagerström; Stockholms universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antifouling paint; XRF; leisure boat; recreational boating; copper; zinc; tributyltin; organotin compounds; risk assessment; biocide; metals; release rate; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The use of biocidal antifouling (AF) paints is the most common way to prevent fouling on leisure boat hulls. The main aim of this thesis was to investigate the pathways through which AF biocides, past and present, may reach the environment through their use on leisure boats and to improve the risk assessment of biocidal AF paints intended for amateur use.

  5. 5. Bioactive Compounds from the Marine Sponge Geodia barretti Characterization, Antifouling Activity and Molecular Targets

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Martin Sjögren; Uppsala universitet.; [2006]
    Keywords : Pharmacognosy; Geodia barretti; barettin; secondary metabolites; settling inhibition; Balanus improvisus; analogs; 5-HT; Farmakognosi;

    Abstract : The marine sponge Geodia barretti produces a range of secondary metabolites. Two of these compounds were isolated and elucidated guided by their ability to inhibit settlement of cypris larvae of the barnacle Balanus improvisus. READ MORE
