8.5 Influence of a Boundary on Added Masses of a Propeller 351 Fig. 8.15 Coefficients of added masses of a propeller with blade-area ratio 0 . 61 under its motion near a hard boundary Disc Moving Near a Flat Boundary Consider a disc or diameter D situated at a distance h from the solid plane; the angle between the plane and the axis of the disc is denoted by ϕ (see Fig. 8.10 ). The model of the disc with the triangulation is shown in Fig. 8.11 . The total number of triangles in the triangulation equals 8056. Computations were performed for different values of relative distance of the disc to the boundary h/D and angle ϕ . The ratio λ 11 11 as a function of h/D and ϕ is shown in Fig. 8.10 .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
