A Molecular Dynamics Simulation of 2D Flow Around a Cylinder

A Molecular Dynamics Simulation of 2D Flow Around a Cylinder

by Gang Pan of the Department of Mechanical and Aerospace Engineering.

This simulation consists of 130,000 particles of 4A. diameter flowing around a cylinder that is 16 microns in diameter. The molecules interact through a Lennard-Jones potential at a Knudsen number of order 1 and a Reynolds number of order 0.1. The simulation is about 100,000 timesteps in duration, or about 1 nsec.
