Determination of Concentration Field Formed with an Intermittent Methane Jet by a Rayleigh Scattering Technique

Abstract

In order to reveal the basic aspect of development and mixing behavior of an intermittent gas jet, an experimental and analytical study was conducted. A Rayleigh scattering technique using a KrF excimer laser was used to determine the fuel distribution of an intermittent methane gas jet injected into an atmosphere. The concentration distribution obtained experimentally was compared with the simulation results in order to evaluate the validity of the simulation, which may possibly be applied to a gas engine combustion study.
