โœฆ Synopsis

Both empirical and theoretical (thermodynamic) investigations indicate that the soil-water characteristic curve (SWCC) is an essential element in unsaturated soil modeling and it is hysteretic in nature, owing to the energy dissipation during moving fluids in or out of the soil. Because of its fundamental significance, this hysteretic feature can no longer be ignored in unsaturated soil modeling. This note presents a simple phenomenological approach for modeling hysteretic SWCCs following arbitary wetting/drying paths.

An unsteady state heat conduction model with a convective boundary condition is proposed for the drying of low-rank, high-porosity coals, such as Iignites, during fluidized-bed combustion. The drying front is assumed to be the receding surface of a wet core. The solution technique for this moving bo
