Spatially-resolved temperature, species, and pressure measurement for reacting flows using ultrafast CARS
Abstract
The design of future propulsion systems such as scramjet engines requires an improved understanding of how fuel and air react and interact with the surrounding flow in a highly compressible, turbulent environment. Experimental investigation of supersonic combustion requires the accurate measurement of key thermodynamic properties—including temperature, pressure, and species concentration—without modifying the combustion reactions or perturbing the flow. Each of these parameters must be resolved locally and within a single instant to study how the thermodynamic state varies in time and throughout space. These measurements will provide new physical insights and validate turbulence models for the simulation of turbulent combustion in compressible flows.
