Nonstationary Flows of Viscous Fluids through Porous Elastic Media. Homogenization Method
Volume: 388
Series: A29
Porous media found in the natural environment represent a good example of media with microstructure. Their pores contain different phases of liquids and gases filling them as well as the interfaces between the phases. This issue has been frequently discussed by soil physicists and chemists, chemical and petro engineers, seismologists and other researchers interested in geosciences.
