Abstract

Laminar fuel-air counterflow diffusion flames (CFDFs) were previously studied using axisymmetric convergent-nozzle and straight-tube opposed jet burners (OJBs) and selected diagnostic techniques. Strain-induced extinction limits (flame strength) were determined for N₂-diluted H₂ versus clean air, and also H₂ versus contaminated-air, to assess” possible effects of air contaminants from test facilities on flameholding processes in H₂-fueled supersonic airbreathing combustors.
