Experimental and numerical investigation of non-submerged flow under a sluice gate
Journal Title: Annals of Warsaw University of Life Sciences – SGGW. Land Reclamation - Year 2015, Vol 47, Issue 3
Abstract
The problem of sluice gate flow is analyzed using two models: a simplified one, derived according to the concept of the Potential Field (PF), and a more complex form, based on the Reynolds Average Navier-Stokes (RANS) equations. The numerical solution is compared with experimental data, including measurements performed by authors and results acquired from literature. Despite its simplicity, the PF model provides a satisfactory agreement with the measurements. The slightly worse performance of the RANS model comes from an overestimation of energy losses.
