“…The changing of saturation, velocity, stress, and temperature field in fractured porous media is directly relevant to reservoir recovery and production. In this special issue, El-Amin [6] developed analytical solutions for magnetic polymer transport in porous media, in which the magnetization was treated as a nonlinear function of the magnetic field strength and the effects of the magnetic/polymer/rock properties on the polymer concentration, pressure, and velocity were investigated. Gao et al [7] proposed a new thermodynamically consistent energy-based model for two-phase flows in heterogeneous and fractured media, which was free of the gradient energy.…”
