%X This review considers
unexpected destructive disasters involving fluid power plants, such as nuclear
electric power plants and fluid power plants. It specifically addresses the
possibility of fluid vibration induced in a pipeline network of such a plant.
The authors investigate the flow oscillation induced within a T-junction for
laminar steady flow at a Reynolds number less than 10<sup>3</sup> and clarify
that there is a periodic fluid oscillation with a constant Strouhal number
independent of several flow conditions. Generally, a nuclear electric power
plant is constructed using straight pipes, elbows, and T-junctions. Indeed, a
T-Junction is a basic fluid element of a pipeline network. The flow in a fluid
power plant is turbulent. There are peculiar flow phenomena that occur at high
Reynolds numbers, which are also seen in other flow situations; e.g., Kaman
vortices are observed around a circular cylinder in low Reynolds numbers,
around structures like bridges and downstream of islands in oceans. Although
the flow situation of a T-junction and elbow in a fluid power plant,<span style=\"color:red;\"> </span>such as the fluid suddenly changing its flow
direction is turbulent flow, the authors mention the possibility of the
fluid-induced vibration of a pipeline network.
