A new mechanism of viscoelastic fluid for enhanced oil recovery: Viscoelastic oscillation
نویسندگان
چکیده
This report summarizes our recent experimental findings [Xie et al., Phys. Rev. Lett., 2022] and pore-scale simulation results Fluids., 2020] on viscoelastic oscillation, which is a new observation of instability in the multiphase flow state. The oscillation causes trapping droplets contraction-expansion micro-channels regardless injection rate. Based force balance analysis viscous, capillary elastic forces, amplitude found to linearly increase with viscoelasticity, trapped droplet size determined by elasto-capillary number. also helps extract from their originally positions such as dead-ends once critical Deborah number reached. These successfully explain phenomenon that alternative inelastic fluids continually produces additional oil, indicating important mechanism fluid for enhanced oil recovery.

Enhanced displacement of a liquid pushed by a viscoelastic fluid.
We consider the displacement, in a rectangular channel, of a Newtonian oil pushed by different types of liquids (Newtonian, shear-thinning, viscoelastic) of slightly higher apparent viscosity. In the absence of viscoelastic effects the interface between the two fluids becomes sharper at larger velocities, so that the thickness of the lateral film left behind increases with the flow rate. On the...
متن کاملInfluences of magnetic field in viscoelastic fluid
This communication influences on magnetohydrodynamic flow of viscoelastic fluid with magnetic field induced by oscillating plate. General solutions have been found out for velocity and shear stress profiles using mathematical transformations (Integral transforms). The governing partial differential equations have been solved analytically under boundary conditions u(0,t)=A_0 H(t)sinΩt and u(0,t)...
متن کاملPropulsion in a viscoelastic fluid
Flagella beating in complex fluids are significantly influenced by viscoelastic stresses. Relevant examples include the ciliary transport of respiratory airway mucus and the motion of spermatozoa in the mucus-filled female reproductive tract. We consider the simplest model of such propulsion and transport in a complex fluid, a waving sheet of small amplitude free to move in a polymeric fluid wi...
متن کاملIssues in Viscoelastic Fluid Mechanics
Polymer solutions and melts are viscoelastic; they exhibit fluidlike behavior in steady shear, but the initial response to an imposed deformation involves a material-dependent transient that may be many orders of magnitude longer than time scales associated with instrument inertia. Intrinsic material time scales can be identified with the dynamics of the macro molecular chains. Shaping process...
