Autor: Masatoshi Yuhi, Shinya Umeda, Hajime Ishida

Publikováno v: 土木学会論文集B2(海岸工学) = Journal of Japan Society of Civil Engineers, Ser. B2 (Coastal Engineering). 65(1):786-790

We have developed a three-dimensional numerical model for temporal developments of flow and scour around a slender pile exposed to oscillatory flow. The flow model is based on the Navier-Stokes equations in moving generalized curvilinear coordinate s

The instability and transition of flow past two circular cylinders arranged perpendicularly to the stream are investigated numerically. It is a steady symmetric flow that is realized at small Reynolds numbers, but the flow becomes unstable above a cr

Control of oscillatory thermocapillary convection

Autor: Shiomi, Junichiro

Possibility to stabilize the oscillatory thermocapillary convection is demonstrated using a proportional feedback control. The feedback control is realized by locally modifying the surface temperature by using the local temperature measured at differ

Seeding the flow with tracer particles is a common way to visualize the flow in a half zone liquid bridge. In the experiments on the ground, these tracer particles were found to accumulate and form a rotating closed loop when the flow field is three
