Channel formation in draining suspensions

We analyse how particles adhering to a wall can create tree-like structures (or flat trees) by an erosive flow. We vary the physical and chemical properties of the fluid and highlight their influences on the patterns observed. We analyse the structures created and conclude that the mass concentration in particles have a clear impact. Using the fractal dimension defined by the box-counting process, we prove that the tree-like patterns are fractal objects. An interesting fact is that this fractal dimension remains constant at a fixed height of analysis.
