Abstract
A new physico-mathematical approach is developed for modelling of fuel migration in an axisymmetric groundwater flow by considering the various dimensionless parameters governing the transport processes. The self-similar solution scheme developed for a time-dependent water injection rate describes the evolution of the fuel saturation in the aquifer near a single recharge well. It is found that the capillary forces prevent the fuel from being removed downstream by injecting water through the well. The time dependent saturation profiles calculated from several exact analytical solutions exhibit the effects of various dimensionless parameters in fuel migration in radial water flow.
