  1. 1. Computational Analysis of Spray Deflector Designs

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Osman Gyokhan Ali; [2023]
    Keywords : Planing Hulls; Spray Deflector; Hull Modification; Computational fluid dynamics CFD ; resistance; trim angle; heave; CD-adapco Star CCM ; Numerical Ventilation; Phase Replacement; Modified HRIC Scheme; Volume Fraction Source Term; Reynolds averaged Navier-Stokes RANS ; Volume of Fluid VOF ; SST K-Omega Turbulence Modelling; Höghastighetshantverk; modelldesign; spraydeflektor;

    Abstract : Planing hull is a common hull design concept which decreases the resistance while speed is increasing for a specific speed range. It is also suitable for hull modifications to achieve higher efficiency. Spray deflector is a promising hull modification which offers extra resistance decreasing and less vertical acceleration for planing hulls. READ MORE

  3. 2. Model Design for Further Spray Deflector investigation

    University essay from KTH/Marina system

    Author : Xinguo Wang; [2021]
    Keywords : High-Speed Craft; Model Design; Spray Deflector; Höghastighetshantverk; modelldesign; spraydeflektor;

    Abstract : Planing hull is one solution to break the speed barrier of conventional hull, but as the boat reaches a high speed, massive whisker spray will be developed and attached to the hull, which causes a notable resistance increase. A Swedish company Peterstep invented an innovative spray deflector that can deflect the spray backwards and harvest kinetic energy from the spray. READ MORE

  4. 3. Experimental Validation of Innovative High-Speed Craft Spray Deflectors

    University essay from KTH/Marina system

    Author : Fran Osmak; [2020]
    Keywords : ;

    Abstract : Hydrodynamic analysis of high-speed craft is a complex problem. For years naval architects have tried improving the eÿciency of the hull, changing its form, the number of hulls, adding spray rails or steps. READ MORE

  5. 4. Experimental Evaluation of Spray Reduction Technologies

    University essay from KTH/Marina system

    Author : Svante Lundmark; [2019]
    Keywords : ;

    Abstract : This report concerns the efficiency of a novel spray deflector design. The novel design is analyzed and compared to a bare hull and a bare hull fitted with spray rails by experimental testing in a towing tank. READ MORE

  6. 5. Benchmark Testing of Spray Deflection Technologies for High-Speed Planing Craft

    University essay from KTH/Marina system

    Author : Bogdan Molchanov; [2018]
    Keywords : ;

    Abstract : High-speed planing craft is designed to overcome conventional hull’s speed barrier associated with wave making resistance and high frictional forces. Despite being able to reach high speeds, some planing hull forms will develop large volumes of spray attached to the hull surface, which can account for a large proportion of the total resistance.
