  • The results of this study suggest that the accuracy of Gassmann's fluid substitution remains adequate for a wide variety of highly porous rocks even if the contrast between the elastic properties of mineral constituents is large.While Gassmann's fluid substitution is robust for rocks saturated with Newtonian fluids (brine, gas, light oil), it breaks down for viscoelastic fluids such as heavy oils.

  • It can be recommended not only to specialists in the field, but it can also be used for doctoral students and young researches who want to start to work in the mathematical theory of compressible fluids and their asymptotic limits. (springer.com)
  • In this talk, we first make an extensive investigation of the viscous drag/drainage with smooth rods. (aps.org)
  • The micro-structures has several purposes: to trap fluid in the controlled roughness, and to alter the viscous drag process. (aps.org)
  • For molecules whose size is comparable with the extracellular cleft, the predominant effect is the viscous drag of the cell walls. (pnas.org)
  • Except that the drag option will slow down fluid when inside of a force field. (blenderartists.org)
  • The invasion of one fluid into another of higher viscosity is unstable and produces complex patterns in a quasi-two dimensional geometry. (aps.org)
  • In the absence of such a coupling, the viscous stress tensor will have only two independent parameters and will be symmetric. (wikipedia.org)
  • While the viscous stresses are generated by physical phenomena that depend strongly on the nature of the medium, the viscous stress tensor ε is only a description the local momentary forces between adjacent parcels of the material, and not a property of the material. (wikipedia.org)
  • While we are on that wp artikel, this en.wikipedia.org/wiki/Honey#Rheology is of course highly relevant. (stackexchange.com)
  • An alternative fluid substitution scheme for rocks saturated with viscoelastic fluids based on self-consistent effective medium theory is proposed in this thesis. (edu.au)
  • In particular, computation of these bounds shows that dispersion and attenuation in a rock saturated with a fluid (viscous or viscoelastic) can be much stronger than in the free fluid. (edu.au)
  • When sound propagates in structures and geometries with small dimensions, the sound waves become attenuated because of thermal and viscous losses. (comsol.com)
  • When modeling the response of small transducers, like condenser microphones, MEMS microphones, and miniature loudspeakers, it is necessary to include thermal and viscous losses. (comsol.com)
  • The modeled transfer impedance of the coupler is shown in blue, including thermal and viscous losses, together with the prescribed standard curves in red and the curve resulting from a pure lossless model in green (right). (comsol.com)
  • To model these effects, it is necessary to include thermal conduction effects and viscous losses explicitly in the governing equations, solving the momentum through the Navier-Stokes equations ), mass (continuity), and energy conservation equations. (comsol.com)

  • The kinematic viscosity (also called "momentum diffusivity") is the ratio of the dynamic viscosity μ to the density of the fluid ρ. (wikipedia.org)
  • Ignoring the torque on an element due to the flow ("extrinsic" torque), the viscous "intrinsic" torque per unit volume on a fluid element is written (as an antisymmetric tensor) as τ i j = ε i j − ε j i {\displaystyle \tau _{ij}=\varepsilon _{ij}-\varepsilon _{ji}} and represents the rate of change of intrinsic angular momentum density with time.
