Direct numerical simulation of a turbulent lean premixed CH4/H-2-Air slot flame

摘要

Nowadays, in the context of CO2 reduction and gas turbine fuel flexibility, the interest in acquiring knowhow on lean Hydrogen Enriched Natural Gas (HENG) is growing. This article provides a detailed analysis of two turbulent (Re-jet = 2476, Re-t = 236) lean (Phi = 0.7) CH4/H-2-air premixed slot flames (unconfined and at atmospheric pressure) highlighting the effects of two different hydrogen contents in the inlet mixture (20%and 50% by volume respectively for flames named A and B).
