title = "Capillary dynamics of elastic-wave-enhanced two-phase flow in porous media",
abstract = "Elastic waves may enhance two-phase flow in porous media. We investigate the role and dynamics of capillary forces during the enhancement process. We present a theory that allows us to estimate the response of trapped nonwetting phase blobs to variable frequency excitation. According to this theory capillary trapped oil blobs may exhibit resonance, depending on the properties of the fluids and the pore space. Using this theory we estimate the resonant frequencies of crude oil and gasoline blobs in sphere packings. We will also present experimental evidence showing that capillary trapped liquid blobs exhibit resonance.",
