Research Abstract

In this study, the general expression for the drag coefficient of various bodies in aerated flows is reasonably established on the basis of flow characteristics of aerated flows. Also, in stepped channels, drag coefficients of various cylindrical bodies and a model leg are obtained from aerated flow characteristics.
