Abstract

Eulerian and Lagrangian simulation of transport phenomena in multiple or periodical interacting planar jets and wakes versus experimental results A. Cavaliere", G. de Felice\ F.M. Denaro\ C. Meola& Napoli, Italy ABSTRACT The experimental flow visualization of mixing phenomena in an array of planar jets has been carried out and compared with the corresponding numerical patterns obtained through flow simulation. To allow a correct evaluation of the results a theoretical analysis relative to Lagrangian as well as Eulerian approaches has been outlined. Qualitative comparisons indicate good agreement between experimental and numerical patterns. INTRODUCTION The modeling of mixing phenomena inside unsteady shear flows and wakes is a fundamental prerequisite in order to perform an effective analysis and control of the mixing itself and of many correlated processes like flames, water or air pollution etc. The determination of a simple convective mixing even when it is produced by
