| Abstract: | Convective-dispersion process is scale-dependent.The dispersion properties measured in different space-time scales are different. It always is an important research topic to determine dispersion property in macroscale structure (simulation scale) and in megascale structure (field-scale) on dispersion property in microscale pattern (experiment scale). The scale-up of dispersion property is researched with stochastic process and central limit theorem. The general theory and method are discussed. |
