[USCC] pressure loss in the compost body

[e.denboer@web.de]

Dear All,

I work on a concept for a forced aeration system in a kind of box composting system, in which household biowaste (kitchen + green waste) is supposed to be composted. I would be grateful if somebody could provide me with some realistic data for pressure of air flowing though the compost body in a vertical direction. I was trying to use the Ergun equation to calculate it, but I am also lacking realistic data for the air-filled porosity and the specific particle size of biowaste. I guess in this case empirical data for the pressure drop would be better than the theoretical one,

I am looking forward to your answers,
kind regards,

Emilia den Boer
