Advanced Penetration Problems. Volume 3. Exothermic Additives for Wake Modification

Abstract

An investigation has been undertaken to study, in a well-defined laboratory situation, the influence of chemistry on turbulence structure in compressible flows. The principal effort has consisted of the design of experiments for demonstrating the effect of exothermic energy release on turbulent flow structure, the development of sensitive instrumentation for the accurate measurement of both time-average and fluctuating scalar quantities (temperature and concentration), the development of techniques for reducing the raw data derived from the sensors and their associated electronics to forms suitable for correlation and analysis, and the completion of several experiments under 'self-mixing' conditions without injection and under wake conditions with and without injection. Calculations of the effectiveness parameter for the NO2 reacting system have shown that the recombining NO2 system (to form N2O4) will exhibit a sufficiently large effectiveness parameter under laboratory conditions so that the turbulence in a wake flow should be significantly modified.
