Chemistry Implications from Optical Diagnostics in Engine Research 911784

Modern optical diagnostics such as laser induced fluorescence (LIF) offer considerable assistance in developing effective computational capabilities for complex reactive flows. Applications of these selective, spatially-resolved, non-intrusive technologies include model verification, input parameters, and kinetic simplifications for complex calculations. Pertinent examples from our current diagnostics development and flame applications are reviewed with an emphasis on the chemical implications to advanced computational dynamics for engines. Raman, LIF, and chemiluminescence diagnostics are discussed; potential diagnostics applications include fluid mixing, pollutants, knock, flame front location, and temperature measurement.
