### The Lattice-Boltzmann Method for Gaseous Phenomena

Paper by Xiaoming Wei, Wei Li, Klaus Mueller and Arie Kaufman

Implementation by Davey Krill, March 2006, CS 777

Problem and Goal

Temperature Field simulates Buoyancy

Velocity Field simulates Wind

Display Particles

Boundary Conditions

Microscopic Particles

The Algorithm
• Initialize the grid cells
• Find
• Compute equilibrium packet distributions
• Solve for new packet distributions
• Propagate to neighboring cells
• Boundary conditions
Putting it to the Test

Initial conditions: D=0.42, v=0.5, tau=0.56
