    Abstract

    How is it possible to modelise a free moving rigid body in a fluid? This problem does not have any open source solution available on the internet however it needs to be solved for a lot of applications. A moving object in a flow can be represented by a broken piece moving along the flow. It’s very important to be able to predict where this object is going to move after a while, even more when the fluid is opaque. This report will explain how to extract the problem physics. What is important in our case is to understand what are the forces between the object and the flow and to find how to solve the problem numerically. We will then make an assessment on existing models in order to find the closest tutorial for our model. Afterwards, we will show how to solve the problem and try to develop as much as possible a theoretical model. Finally we will compare numerical/theoretical and experiment in order to validate our numerical models.
