Vortex Hydrosuction: A New Sediment Removal System
Publication: Journal of Hydraulic Engineering
Volume 147, Issue 12
Abstract
In this study, a new sediment removal system, namely the vortex hydrosuction (VHS) method, is introduced as an alternative hydrosuction technique with higher efficiency. Unlike the conventional hydrosuction systems, VHS benefits from a generated vortex flow for suspending the settled particles. The ability of 27 different VHS systems to remove noncohesive sediment is assessed. The results indicate that the efficiency of the best VHS is about 24 times higher than conventional hydrosuction. On average, the VHS increase the volume and depth of scour holes by around 13 and 2 times more than conventional hydrosuction, respectively. Sensitivity analysis of significant parameters indicates that by increasing 100% and 300% of the nozzles’ Froude numbers (), the performance of VHS would increase 43% and 110%, respectively. Moreover, the generated vortices in the cylinders with smaller diameters are stronger compared with cylinders with greater diameters; thus, by increasing 20% and 47% of the cylinder diameter dimensional parameter (i.e., ), the performance of VHS would decrease about 16% and 59%, respectively.
