A Finite-Volume Method for the UnsteadyFlow about a Shipin Generalized Coordinate Systems
Autor: Hideaki Miyata, Hisashi Kajitani, Ming Zhu
Publikováno v: Journal of the Society of Naval Architects of Japan. 1990:9-15
A finite-volume method for a flow about a ship-like body is developed in generalized curvilinear coordinate systems. The conservation of mass and momentum is implemented in generalized coordinate systems with sufficient robustness. The numerical diss

Autor: Mikito Shirai, Hideaki Miyata, Makoto Kanai, Toru Sato, Shozo Kuzumi, Hisashi Kajitani
Publikováno v: Journal of the Society of Naval Architects of Japan. 1983:48-55
A vast amount of numerical and experimental results are presented in this final report. Numerical simulations are performed by the TUMMAC-Vot program to know the effect of Froude number on the breaking bow waves, as well as the effect of shear flow n

Effects of Boundary Layer and Wake on Characteristics of Stern Waves
Autor: Tooru Kitamura, Hisashi Kajitani, Yasuaki Doi
Publikováno v: Journal of the Society of Naval Architects of Japan. 1986:23-31
A numerical analysis is tried how the “waves” and “boundary layer-wake” interacts. External potential flow around a hull is modeled by modified Guilloton method. Viscous flow is modeled by integral boundary layer-wake method. The displacement

Wave Formation about a Ship Bow Advancing in Head Seas
Autor: Hisashi Kajitani, Shunsuke Akifuji, Makoto Kanai, Hideaki Miyata, Mutsuo Haba
Publikováno v: Journal of the Society of Naval Architects of Japan. 1987:10-23
The diffraction of regular waves by an advancing ship bow were studied experimentally and numerically. Diffracted wave patterns were photographically visualized and wave formation was analyzed by the grid projection method. Significant nonlinearities

On the hydrodynamical source singularities for surface ships with special refference to Line Integral
Autor: Takao Inui, Hisashi Kajitani, Yuzo Kusaka
Publikováno v: Journal of the Society of Naval Architects of Japan. 1975:12-22
The equivalent source singularities distributed over the hull are analysed based upon the exact linear free surface condition. The role of “Line Integral” on the Neumann-Kelvin problem is primarily studied, which since Brard's suggestion calls in

Finite-Difference Simulation Method for Waves and Viscous Flows about a Ship
Autor: Hideaki Miyata, Hisashi Kajitani, Nobuhiro Baba, Toru Sato
Publikováno v: Journal of the Society of Naval Architects of Japan. 1986:14-20
A finite-difference method named WISDAM-II is developed for viscous flow about a steadily advancing ship involving free-surface waves. The Navier-Stokes equations in a rotational form are solved by a time-marching scheme in a boundary-fitted coordina
