To analyze the influence of parameters other than IFT and capillary forces, we conducted capillary imbibition experiments on cylindrical Berea sandstone core samples under ultrasonic radiation in this paper. Through this experimental scheme, we focused on (a) the effect of initial water saturation...

... Saturations The transient boundary condition which was anticipated with the new boundary conditions did not occur in Case 2. Numerical dispersion causes the water saturations, originally at Siw, to rise at least infinitesimally, throughout the reservoir on the first time step. In order to observe the effects...
