Abstract-
Using data obtained from PIV and PLIF of CH, this talk discusses the axial
velocity of the flame surface in turbulent jet diffusion flames, the strain
rates, the dilatation and the residence times. The importance of the
stoichiometric velocity, even in turbulent flows, is shown and a simple
physical interpretation is provided. The extension to jets in crossflow at
various injection angles is also discussed highlighting the differences with
jets in coflow.
