[AOS14-08] Numerical Analysis of Submerged Turbulent Buoyant Jet in River Mouth
Keywords:Submerged Turbulent Buoyant Jet, River Mouth, Numerical Analysis, Finite-Difference Methods, Buoyancy, Plume
Our model will be applied to simulated several characteristic behaviors that are consistent with prior knowledge, including: (1) the inflow concentration is higher at the fixed inflow rate and calculation time, the formed buoyant jet has a large influence range and higher concentration; (2) when the inflow rate is high in a fixed flow concentration and calculation time, the generated buoyant jet has a large influence range and that shape more bulging. Moreover, we will adjust the downstream boundary conditions. When the downstream water level is high, the range and the duration time of the buoyant jet are great. As expected, the concentration of the same location is also higher than other situation that has a lower downstream water level. So far, this model will progress to the extent that it can capture the overall trend of buoyant jet movements, and this simulation is based only on the physical mechanism of the sand-containing fluid itself.
