This 4-hour short course will provide a thorough overview of the Direct Simulation Monte Carlo (DSMC) method starting with Bird’s standard 1994 algorithm and progressing through the recently developed “sophisticated” procedures, with examples drawn from hypersonics and microsystems. Alejandro Garcia, San Jose State University, and Michael Gallis, Sandia National Laboratories, will cover the following topics:
Molecular motion
Wall interaction
Collisional energy exchange
Chemical reactions
Meshing and time-stepping
Sampling issues
Numerical implementation
Efficient parallelization
Convergence and accuracy
Common errors and pitfalls
Unsteady flows
Fluctuations
Future trends
