Abstract
The Three Gorges Dam (TGD) constructed at the Yangtze River, China represents a revolutionary project to
battle against the mage-scale flooding problems while improving the local economy at the same time.
However, the large-scale fine-size sediment and pollutant material transport caused by the TGD operation are
found to be inevitable and long-lasting. In this paper, a multi-fluid Incompressible Smoothed Particle
Hydrodynamics (ISPH) model is used to simulate the multi-fluid flows similar to the fine sediment materials
transport (in muddy flows) and water flow mixing process. The SPH method is a mesh-free particle modeling
approach that can treat the free surfaces and multi-interfaces in a straightforward manner. The proposed
model is based on the universal multi-fluid flow equations and a unified pressure equation is used to account
for the interaction arising from the different fluid components. A Sub-Particle-Scale (SPS) turbulence model
is included to address the turbulence effect generated during the flow process. The proposed model is used to
investigate two cases of multi-fluid flows generated from the polluted flow intrusions into another fluid. The
computations are found in good agreement with the practical situations. Sensitivity studies have also been
carried out to evaluate the particle spatial resolution and turbulence modeling on the flow simulations. The
proposed ISPH model could provide a promising tool to study the practical multi-fluid flows in the TGD
operation environment.
