Abstract
The present development of laser diagnostics for combustion and flowfield studies at the Defence Research Establishment Ottawa (DREO), and the future application of these diagnostics to a practical combustion device is described. The optical diagnostics discussed are coherent anti-Stokes Raman spectroscopy (CARS), and various flow/spray visualization (FSV) techniques. The CARS technique provides temporally and spatially resolved measurements of temperature and major species concentrations. Various laser based FSV techniques, such as shadowgraph, Schlieren and direct visualization, and their use to study density gradients and spray behavior are described. The diesel combustion modelling program at DREO is outlined. The constraints on performing optical diagnostics in diesel engines, and the requirements and the selection of a research diesel engine are discussed.
