Assessment of the Ability of a Volume of Fluid Model to Reproduce the Efficiency of a Continuous Transverse Gully with Grate
Publication: Journal of Irrigation and Drainage Engineering
Volume 142, Issue 10
Abstract
This paper deals with the numerical investigation of the drainage efficiency of a continuous transverse gully with the grate’s slots aligned in the flow direction and compared with experimental data sets. The gully efficiency attained with a three-dimensional (3D) numerical model is compared and validated against experimental data. The numerical simulations are performed using a computational fluid dynamics volume of fluid solver. Different slopes, from 0 to 10%, and a wide range of drainage flows, from 6.67 to , are simulated. The linear relation between Froude number and efficiency of the gully is in agreement to the one experimentally obtained.
