The main objective of the present study is to introduce two novel benchmark solutions
namely: two-dimensional three-fluid Rayleigh-Taylor Instability problems, aiming to provide …

We analytically explore the flow of a Newtonian liquid forced to encroach a narrow tube of
uniform cross section, by an unsteady pressure gradient, assisted by an encroachment-rate …

External excitation of oil reservoirs has shown promising potential in increasing residual oil
recovery. Although several numerical, experimental, and pilot studies were conducted over …

Recently, strong sound wave was proposed to enhance precipitation. The theoretical basis
of this proposal has not been effectively studied either experimentally or theoretically. On the …

Fluids in porous media could resonate due to passing seismic waves when meeting certain
conditions of excitation frequency and pore geometry. This study of the resonance of fluids …

Multiphase fluid flow in porous media can be affected by the dynamic stressing caused by
earthquakes or human‐made blasts. Changes in the permeability of porous media can be …

Resonance of droplets in constricted capillary tubes responding to external vibratory
excitation can be theoretically characterized by the abstract coefficients such as resonant …

Contact angle hysteresis (CAH) is a critical phenomenon that could significantly affect the
fate of immiscible bubbles/droplets in vadose zones, nonaqueous phase liquid …
