Joint Probabilities of Two Scalars Emitted from Parallel Jets using Planar Laser Induced Fluorescence

Mike Soltys

Mixing between initially isolated scalars is of great intrest to the field of Civil engineering, with many environmental and industrial applications.  One application of particular intrest is broadcast spawning, the method used by many marine invertebrates to reproduce.  In order to understand and predict the success behind broadcast spawning, a deep understanding of the physics of mixing is necessary.  In this talk, an experimental technique is used to study mixing and reaction between two initially isolated scalars emitted from two parallel jets.  This fundamental problem is used to study the physics of mixing between the two scalars.  Joint probability density functions are examined at key points in the flow to help investigate events that lead to increased mixing between the two scalars.  The results are used to examine development of structures with increased reaction.
