A comparison of Eulerian and Lagrangian schemes for the simulation of an incompressible planar jet

Abstract

In this investigation solutions have been obtained using an Eulerian time accurate fractional step Direct Numerical Simulation (DNS) scheme for a homogeneous incompressible planar jet and the results compared with those obtained using a Lagrangian Direct Simulation Monte-Carlo (DSMC) method. Comparisons were made of various flow features using plots constructed from instantaneous and ensemble averaged data. Details of the schemes, computational requirements and the accuracy obtained with each of the methods will be presented.
