  4. 9. Developing Computational Methods for Detailed Assessment of Cavitation on Marine Propellers

    Författare :Abolfazl Asnaghi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LES; OpenFOAM; Numerical simulation; Hydrodynamics; Cavitation;

    Sammanfattning : Cavitation often brings negative effects, such as performance degradation, noise, vibration, and material damage, to a marine propulsion systems, but for optimum performance, cavitation is almost inevitable. Therefore, it is necessary to improve the understanding of cavitation in order to maximize the performance without encountering severe problems. LÄS MER
