NUMERICAL SIMULATION FOR RADIONUCLIDETRANSPORT INTO A SINGLE FRACTURE INA POROUS FORMATION
放射性核素在多孔岩层裂缝中传输的数值模拟

Cubic spline method was used to solve numerical model for radio-nuclide transport from injection well into a single fracture in a porous formation, and the results were compared with those of finite difference scheme. It is shown that cubic spline method is effective for restraining numerical dispersion in numerical simulation of hydrodynamic dispersion equations with radioactive decay.
