...). Therefore, it is of great significance to study the scale effect of wake field for the rapidity of ships (Froude W, 1872; B.E Launder, 1972; B.E Launder, 1974; Larsson L, 1991; Zhu Renchuan, 2007). Taking the KCS standard ship model as the research object, this paper calculates the wake field at a fixed...
