Research Abstract
Visualized simulation tool of Direct Simulation Monte Carlo (DSMC) is essential in aeronautical engineering and gas dynamics, by presenting information that can educate engineers and scientists to preliminarily understand the molecular gas dynamics and direct simulation of gas flows. Two educational tools and models are described for rarified gas flows and simulated particle collisions. A 0-Dimensional DSMC in approach to translational equilibrium was developed to simulate the speed distribution over time and the comparison between the final distribution and the Maxwell-Boltzmann distribution. A 1-Dimensional DSMC for Planar Couette flow was also developed to calculate the number of strikes of the walls, pressure, and viscosity, compare the viscosity with the theoretical value, and present the number density, temperature, velocities profile, and the speed distribution over time. These two models will help illustrate the basic molecular gas dynamics and direct simulation of gas flows principles. The tool has been created through nanoHUB.org and will be published soon.
