Fluid-fluid interaction during miscible and immiscible displacement under ultrasonic waves

Volume fraction based miscible and immiscible fluid animation

We propose a volume fraction based approach to effectively simulate the miscible and immiscible flows simultaneously. In this method, a volume fraction is introduced for each fluid component and the mutual interactions between different fluids are simulated by tracking the evolution of the volume fractions. Different techniques are employed to handle the miscible and immiscible interactions and...

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...

Ultrasonic Surface and Bulk Wave Interaction with Fluid - Saturated

There has recently been considerable interest in the acoustics of fluid-saturated porous media. The most interesting peculiarity, the existence of two compressional waves, was first predicted by Biot [1] in 1956. It was not until 1980 that Plona [2] experimentally observed the additional slow compressional bulk wave in a water-saturated porous solid composed of sintered glass spheres. Even more...

Displacement-velocity correction schemes for incompressible fluid-structure interaction

We propose a new class of time-marching schemes for the explicit coupling of an incompressible fluid and an elastic solid (not necessarily thin). We state a general energy-based stability result and illustrate the accuracy of the different variants in a numerical benchmark. To cite this article: A. Name1, A. Name2, C. R. Acad. Sci. Paris, Ser.
