There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

The School of Aerospace Engineering will present Dr. Philip Pearce who will give a lecture entitled "The Effect of Gravity on Flame Propagation in Inhomogeneous Mixtures"
In many practical situations involving a propagating flame, inhomogeneities are present in the mixture through which the flame propagates. These inhomogeneities can be caused by fluctuations or stratifications in the temperature, the composition or the flow field. This talk will be concerned with situations where the concentrations of fuel and oxidiser are stratified. In these circumstances, ignition leads to the propagation of a so-called triple flame, which was first observed in the laboratory by Phillips in 1965 [1]. Using both analytical and numerical methods, I will describe how gravity affects the propagation of a triple flame and the stability of its trailing diffusion flame, causing instabilities like those that can be clearly seen in one of the first images taken by Phillips.
