you could model it empirically in Matlab. I was bad in that subject. You’ve got your granulometry results from grinding tests. There’s probably some data on dissolvability on coffee solids. You have the data on basket shape, holes and wall design.
… This computer model may be just used as a bench mark if anything… like, if a modelled distribution is xyz, then extraction is going to be xyz… and from this result you may deduce that it’s not going to make much of a difference anyway.
Also, get an opinion from a mathematical/statistics person because remember, your only going to be as accurate as your least accurate measuring equipment. Like, if you measure with centremeters, you can only accurate to +/- 0.5cm. Depending on the outcome, if you want to keep this scientific, then it may not even be worth all this work.
Im also guessing there would be some movement in grinds as they settle and let water pass through them. So do the grinds actually settle and become equally distributed even if they aren’t perfectly distributed?
PS IMS and VST probably already have their respective CAE models that hold for perfect distribution.
