Experiment and computation on the development of axisymmetric gravity currents
Autor: Nobuhiro Baba, Yosuke Sawano
Publikováno v: 2016 Techno-Ocean (Techno-Ocean).
The development of axisymmetric gravity currents was investigated in experiments and computations. Gravity currents were produced by opening the lock-gate instantaneously and releasing heavy fluid into light fluid. Heavy fluid was visualized with dye

Structure of Head of a Gravity Current (Second Report)
Autor: Sadahiro Kan, Nobuhiro Baba, Tetsuo Katsuragi, Ken-ichi Kitaura
Publikováno v: Journal of the Society of Naval Architects of Japan. 2003:23-29
The structure of the head of gravity currents spreading out in all directions is investigated in the experiment and in the computation by extending the method developed in the previous paper for the two-dimensional gravity currents. A finite volume o

Autor: Sadahiro Kan, Ken-ichi Kitaura, Tetsuo Katsuragi, Mitsuo Kishi, Nobuhiro Baba, Hiroki Hashimoto
Publikováno v: Journal of the Society of Naval Architects of Japan. 2003:13-21
The sand transport that causes the movement and deformation of a sand hill in a periodically oscillating flow is investigated in the laboratory. An experimental technique is developed to assess the variation of the state of concentration of sand part

Gravity Current in an Oscillatory Flow
Autor: Yasunori Sakaguchi, Ken-ichi Kitaura, Nobuhiro Baba, Kouji Kuwajima
Publikováno v: Journal of the Society of Naval Architects of Japan. 2000:193-199
The behaviour of the two-dimensional gravity current in an oscillatory flow is investigated by computation when homogeneous fluid and another fluid of slightly different density were released in a sinusoidally oscillating flow. The incompressible Nav

Three-Dimensional Instability of the Head of Gravity Currents
Autor: Satomi Ito, Nobuhiro Baba, Yasunori Sakaguchi
Publikováno v: Journal of the Society of Naval Architects of Japan. 1999:119-125
The three-dimensional instability of the head of gravity currents is investigated in the experiment and in the computation of lock-exchange flow. Visualization experiments were made with dye to observe the three-dimensional features of the head advan
