Experimental and numerical study of oxidant effect on hythane combustion

摘要

This paper reports on the experimental and numerical results of the hythane diffusion flame enriched by oxygen, realized in a coaxial burner characterized by a central jet of hythane injection with an internal diameter of dfuel = 6 mm and an annular jet of oxidant injection with a diameter of dox = 18 mm. For velocity measurements, the Particle Image Velocimetry (PIV) technology is used. The numerical study is based on the K-6)-SST Turbulent Model and the Eddy Dissipation Model (EDM) for combustion. Firstly, a comparative study is carried out between experimental and numerical simulation of the flow dynamics in the hythane/Air + O2 flame. Secondly, the numerical results show that the oxygen enrichment increases the temperature of the hythane flame and minimizes the formation of harmful gases into the environment.
