Abstract
<p> An intake vortex is entrained air from a water surface, and it causes problems in a hydropower facility due to equipment failure. In a previous research, the authors found that an increase of a velocity in a middle and lower layers of a flow field may be related to an occurrence of an intake vortex. It maybe a key to clarify a cause of an intake vortex. In this study, inner diameters of intake pipes are changed under a condition that a flow rate and water depth are kept constant, and examined how the flow field changes. As a result, it is found that an occurrence of a large vortex such as an intake vortex is related to a number of occurrences of a small vortex and so on.</p>
