Dredging Engineering

2016-03-22

Dredging is a very important activity for mankind, for example deepening waterways or creating artificial islands. The Trailing Suction Hopper Dredger (TSHD) is an important dredging vessel, this vessel uses the so called drag head. It is common practice to use water jets in drag heads to create a more efficient dredging process. Some theoretical and empirical models exist which determine for example the van Rhee jet model which predicts the depth and width of the scour hole created by a impinging jet. The performance of these models is limited such that the production is not estimated correctly. Therefore a lot of effort is done to understand the underlying processes. This thesis project is therefore aiming to provide insight in these quantities using numerical simulations of the flow.
