Abstract

For the characterization of reacting flows, it is essential to obtain accurate species measurements. Obtaining accurate measurements is difficult, due to bias introduced by continued reaction in the sample lines. A sample probe is needed that can reliably quench reactions at the probe tip, freezing the chemical composition for the downstream analyzers. Aerodynamic quenching can be very effective in freezing reactions, but achieving the necessary internal probe conditions to quench the reactions aerodynamically at various conditions can be extremely difficult. In this SBIR program, an innovative design methodology will be used to develop a smart probe configuration with diagnostic output and control characteristics that will allow reaction quenching to be monitored and the operating range of the probe extended. In Phase I, state-of-the-art numerical design techniques will be used to design a prototype probe geometry and evaluate its potential effectiveness in quenching reactions. Prototype hardware will be fabricated and tested in a laboratory setting to demonstrate probe features and operating range. In Phase II, the design will be optimized and tested at supersonic operating conditions, typical of those encountered in scramjets and the exhaust of augmented gas turbines. Testing will be performed at Virginia Tech (Joseph Schetz) and Arnold Air Force Base. Final probes will then be delivered to the Air Force.
