Results are presented from an analytical assessment of the effects of NO and H/sub 2/O in air on the ignition and reaction of hydrogen. Three flow models of the burning process were used, each including a 32 reaction chemistry mechanism. These models were a plug flow reactor to determine ignition and reaction times; a well-stirred reactor to assess flame stability or blow-off, and a parabolic Navier Stokes code to examine the diffusion flame combustion. The diffusion flame was computed for a cold supersonic H/sub 2/ jet coaxial with a supersonic air stream at a static temperature of 1100 K and a pressure of 1 atmosphere. 15 references.
