Numerical Investigation of Pressure Load over Spillway Chutes with Vertical Curvatures

For flow conduits with mild slope and considerably large vertical curvatures the hydrostatic distribution of the pressure may be used for design proposes. However, for the spillway chutes actual pressure load over the steep slope beds with small vertical curvatures may differ from the hydrostatic pressure values. The differences in pressure load on curved bed chutes are mainly because of the centrifugal forces. In present work a two dimensional Finite Volume flow solver, which utilizes the Volume of Fluid technique, is devised to investigate the division of the numerically computed pressure from the hydrostatic assumptions using some measurements for laboratory test cases reported in the literature.
