Краткое описание

A mathematical model has been proposed for numerical simulation of composting processes under aeration controls. Exploiting the local volume-averaging theory, an appropriate set of governing equations has been introduced so as to describe complex transport phenomena associated with microbe species, substrates, and water in composting operations. A two-dimensional numerical experiment has been conducted to reveal the temporal and spatial variations of the system temperature, substrates, and microbial concentrations within an open channel-type composting system, aerated by forced ventilation. The effects of mechanical agitation on the composting process have also been investigated in terms of temperature and concentrations over the pile cross section.
