Abstract:

HIGH TEMPERATURE CHEMICAL KINETICS IN LAMINAR FLAMES High temperature chemical kinetic information was obtained by means of the detailed analysis of laminar flame structure. Work has continued on developing a scavenger probe technique for H-atoms. A preliminary profile of H-atom concentration in a spherical CH4-O2 flame was obtained, as were several results on H-atoms generated in an electrodeless discharge. THERMAL CONDUCTIVITY OF GASES High temperature gas thermal conductivity measurements by means of a line source in a laminar flow are being carried out. Data on CO2-N2 mixtures are being obtained. ROCKET NOZZLE FLUID DYNAMICS Experimental measurement was made of the flow properties in a rocket nozzle employing a typical solid propellant. Previously noted differences between the experimental and theoretical pressure distribution in the standard 25 degree nozzle was studied and discussed. IR spectroscopic results were obtained in the nozzle, both in situ and in gases sampled from the flow.
