Abstract

In this article, the results of computational fluid dynamic (CFD) modelling of the hydraulic jump conditions occurring in the experimental prismatic rectangular stilling basin with sudden crosswise expansion are presented. The FLOW 3D software program was used to numerically solve Reynolds Navier-Stokes (RANS) equations with the application of the k-ε turbulence model. The influence of the depth magnitude of the stilling basin and the ending sill installation on the hydraulic jump turbulent characteristics and submergence condition changes was investigated. Based on the results of the numerical modelling, it was found that various spatial flow processes contribute to the submergence condition of the hydraulic jump. These processes include: crosswise flow expansion within the stilling basin; local tail water surface level increase and total head loss due to vertical flow contraction; installation of the additional terminal sill. This contribution to the submergence condition allows a reduction in the required depth of the stilling basin, calculated on the basis of a one-dimensional simplified approach without consideration to the spatial characteristic of the hydraulic jump.
