Behaviour of acceleration waves in a viscoelastic porous medium with a structure. Part I – Propagation conditions and growth equations
The behaviour of acceleration wave in a fluid-saturated porous medium with a structure determined by two parameters has been studied. The considerations are based on the description of a geometric structure of such a medium proposed by Kubik (1986a), who characterized the structure of a porous medium by two parameters: volume porosity and a structural permeability tensor.
Using the theory of singular surfaces the propagation conditions of acceleration wave are formulated and the growth equations are derived.
