摘要:Turbidity currents may be a relevant lever to manage the accumulation
of fine sediments in reservoirs. In this paper, we propose to show how
two different numerical codes simulate the propagation of turbidity currents.
Telemac 3D and Ansys CFX 17.1 solver were chosen as they are commonly
used by many research and engineering teams. The simulations are performed
on two configurations. The first case aims at modeling the plunging of a turbidity
current. The second model is validated based on an experimental work
performed at EPFL. The latter consisted on testing turbidity current venting as a
solution to manage reservoir sedimentation. A long and narrow flume was used
to simulate the reservoir where a turbidity current was triggered. The advantages
and limits of both approaches are discussed in order to supply guidelines
for the modeling of turbidity currents in real reservoirs.
