Project Title: Multi-models approach to scour in dynamics areas
Doctoral Candidate: Nishchay TIWARI
Project Description: This PhD research focuses on improving scour depth prediction around coastal structures using SedInterFoam, a three-phase Eulerian CFD model that resolves interactions between water, air, and sediment. Incorporating µ(I) rheology, the model accurately captures dense sediment transport processes, bedload dynamics, and turbulence-induced scour. The study applies this approach to structures like cofferdams and monopiles under combined wave-current flows, simulating complex features such as horseshoe vortices, flow separation, and bed shear. Validated against experimental data, the work enhances understanding of scour mechanisms and delivers a robust framework for predicting scour evolution in engineering- scale coastal environments.
