Abstract:
A numerical model based on the full Navier-Stokes equations is developed to study the dynamics and deposit patterns of turbidity currents. The equation system is simplified using the dilute flow condition which allows one set of momentum equations. The model allows to simulate multiparticle flows in an ambient of pure or sea-water. The solution of the mathematical model is done extending the Characteristic-Based-Split (CBS) Finite Element algorithm to particle-laden flows. The algorithm is implemented by developing a computer program coded in Fortran 90. Additionally, a Box model based on mass balance is developed, which allows to account for the sedimentation, multiple particles and slope changes. Two dimensional and radial flows can be modelled using the proposed Box model just by changing the initial and boundary conditions. The confidence of both the Navier-Stokes based model and the mass-balance based Box model are successfully tested using laboratory experimental data.
