Gaseous isotope separation using solar wind phenomena

Two-dimensional simulation of gaseous phenomena using vortex particles

This article presents a simple, fast and stable method for the animation and visualisation of turbulent gaseous fluids in two dimensions. We draw on well known methods from computational fluid dynamics to model the fluid using vorticity and velocity fields. While the vorticity is transported by a particle system, we use a uniform grid to compute velocities and displacements for each particle. T...

Isotope Effects, Isotope Separation and Isotope Fractionation

A General Animation Framework for Gaseous Phenomena

This paper presents a new animation framework for the modeling of gaseous phenomena. We combine particle and grid based techniques in an innovative way. Based on this framework, our system allows for an incremental design of animations. In the first stage, an animator uses particle methods to model the evolution and appearance of gases. Grid based techniques are subsequently employed to compute...

Simulation of Large Crowds Including Gaseous Phenomena

Crowd animation and simulation have been widely studied over the last decade for many purposes : populating collaborative virtual environments, entertainment and special effects industry and finally simulating behaviors and motion of people in emergency situations for safety systems. This last topic is addressed in this paper. We propose an original enhancement of a well known physics-based ani...

The Lattice-Boltzmann Method for Gaseous Phenomena

We present a physically-based, yet fast and simple method to simulate gaseous phenomena. In our approach, the incompressible Navier-Stokes (NS) equations governing fluid motion have been modeled in a novel way to achieve a realistic animation. We introduce the Lattice Boltzmann Model (LBM) which simulates the microscopic movement of fluid particles by linear and local rules on a grid of cells, ...
