Hey all,

I am trying to build a scrub pad which can scrub oily-dirt off the floors. The Scrub pad is fed water to make it wet, and this is through a controlled water flow. The scrub pad is held against the floor and floor is expected to be clean by to-and-fro motion of the scrub pad. The aim is to develop a scrub material optimized for this application. For this, I want to set-up a digital prototype before I begin with Material design. With this, I can then vary & find out the optimal material properties of the scrub pad.

Case:
The Scrub material (rectangular, foam-based) gets wet by the water which is fed directly to it from above with some pipes. I want to simulate the flow within the material (as the porosity and permeability is known). Then couple this flow field with a FEA Study, where a translatory mesh motion is given to analyze the stress contours on the bottom of the scrub pad, to get an idea on its scrubbing efficiency. I am also exploring coupling with DEM to model the oily-dirt (but keeping this on the backhand for now).

I want to know if my approach is right? OR is there any other simpler way to get the basic understanding of scrub? Any help is appreciated.
