| Abstract: | This paper deals mainly with hydrodynamic dispersion. Based on the analysis of the experiment results and the widely used formulas for calculating dispersion coefficients reported in the literatures, two improved methods are presented for determining the coefficients. The relational expression of flow rates and dispersion coefficient has also been developed for similar cores. |
