Large Eddy Simulation of an Ammonia Jet

Abstract

A compressible jet flow of ammonia was studied through a series of Large Eddy Simulations. Simulations were focused in the zone where the inertial effects are much bigger than the gravitational ones. The ammonia jet is discharged into an air medium and the gases are treated as a two non-reactive ideal gas mixture. Different simulations were performed, going from the use of constant transport properties to the use of kinetic theory of gases relations for calculating them as a function of the resolved variables. The main goal of the present study is to investigate the effect of varying density as well as variable transport properties on the turbulent flow behavior.
