Review: Prediction of Unexpected Fluid-Induced Vibration in Pipeline Network ()
ABSTRACT
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 103 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, 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.
