The angle of internal friction was set to be default of 0.3. The Gidaspow model, Lun et al. model and Schaeffer model were used for granular viscosity, bulk viscosity and frictional viscosity, respectively.
WebCohesive granular materials such as wet sand, snow, and powders can flow like a viscous liquid. However, the elementary mechanisms of momentum transport in such athermal particulate fluids are elusive. As a result, existing models for cohesive granular viscosity remain phenomenological and debated. WebIn science and engineering, hydraulic conductivity (K, in SI units of meters per second), is a property of porous materials, soils and rocks, that describes the ease with which a fluid (usually water) can move through the pore space, or fractures network. It depends on the intrinsic permeability (k, unit: m 2) of the material, the degree of saturation, and on the …
