Mathematical modeling of low-temperature drying of a peatlayer
A one-temperature mathematical model for drying of a peat layer isproposed. Peat is considered to be a multiphase media consisting of a dry organic substance, freeand bound water, and gas phase. The iterated-interpolation method is used to solve numericallythe mathematical model.
