Virtual Sponge Models

Introduction

In this section we model the water flux in living sponges. As we could not test our constructs in living sponges (sponges are fragile organisms, bringing them to paris and then growing them is complicated), we relied on models in order to find out: what would be the effectiveness of our constructs in living sponges ?

To answer this question, we built two different model :

1. A simple model where we consider only water flows without trying to take into acount the very specific geometry of the sponge.
2. A 2D diffusion model where we take into acount the geometry of the sponge.

Throughout this section we base our study on the Spongia Officinalis sponge, because i) there are evidences that pseudovibrio bacteria live inside (TODO: cite) and ii) its is a quite common type of sponge.
