Paper Abstract

Laser diagnostics experiments are described for obtaining multi-dimensional measurements in turbulent flows and flames. Techniques for mapping scalar fields in two and three dimensions are described and examples of measured quantities are presented. Additionally, the temporal evolution of a three-dimensional gas concentration field was measured in an acoustically forced flow, essentially providing a four-dimensional measurement of the flow. A technique for extending this approach to measurements in more general turbulent flows is proposed.
