Seismoelectric couplings in a poroelastic material containing two immiscible fluid phases

Body waves in poroelastic media saturated by two immiscible fluids

A study of body waves in elastic porous media saturated by two immiscible Newtonianfluids is presented. We analytically show the existence of three compressionalwaves and one rotationalwave in an infinite porous medium. The first and second compressional waves are analogousto the fast and slow compressionalwaves in Biot's theory. The third compressionalwave is associated with the pressure diffe...

Axially Symmetric Vibrations of a Liquid-Filled Poroelastic Thin Cylinder Saturated with Two Immiscible Liquids Surrounded by a Liquid

This paper studies axially symmetric vibrations of a liquid-filled poroelastic thin cylinder saturated with two immiscible liquids of infinite extent that is surrounded by an inviscid elastic liquid. By considering the stress free boundaries, the frequency equation is obtained. Particular case, namely, liquid-filled poroelastic cylinder saturated with single liquid is discussed.  When the waven...

Lipid Composition in Miscible and Immiscible Phases

A loosely-coupled scheme for the interaction between a fluid, elastic structure and poroelastic material

The interaction between a fluid, elastic structure, and poroelastic material plays a fundamental role in many biomedical applications. An example of such application is the interaction between blood, arterial wall and blood clot. This multi-physics problem features three different types of coupling: fluid-elastic structure coupling, fluid-poroelastic material coupling, and elastic structure-por...

Fluid-Fluid Collision for Particle-Based Immiscible Fluid Animation

In this paper, we propose a new fluid-fluid collision model for particle-based immiscible fluid animation. Our model consists of two components, namely, collision detection and collision response. An interesting feature is that our model not only can prevent immiscible fluids from mixing with each other, but also can allow one fluid to run through or to wrap around another fluid. The model is v...
