  2. 2. Systematic variations of parameters affecting waterjet-hull interaction

    University essay from Chalmers tekniska högskola/Institutionen för sjöfart och marin teknik

    Author : Johan Andersen; Gustav Moe; [2014]
    Keywords : waterjet; STARCCM ; STREAMLINE; 2DOF; finite volume method; waterjet-hull interaction; net thrust; thrust deduction; hull efficiency;

    Abstract : The purpose of this thesis is to follow a methodology in which computational models with two degrees of freedom (2DOF), based on the finite volume method, are validated and used to investigate how certain phenomena and parameters, especially the longitudinal position of the waterjet intake, affect resistance and thrust deduction (t) for the STREAMLINE hull. To arrive at a scientific answer to this question a methodology is carried out comprised of a grid dependence study followed by three studies of systematic variation. READ MORE
