Abstract

In this paper, we present a numerical investigation of dam-break waves during the initial stage. The numerical model is based on the Reynolds Averaged Navier-Stokes (RANS) equations with a k-ε turbulence closure model (J. Fluid Mech. 359, 1998, 239). Numerical results are compared with existing experimental data (J. Fluid Mech. 374, 1998, 407) as well as the new experimental data. Good agreements are observed. The effects of the water depth in front of the dam and the pull-up motion of dam on the generated waves are then investigated. The turbulence associated with the dam-break waves is also discussed.
