A model for hydrogen combustion intended for low-resolution calculations will be treated in this presentation. The modeling includes the effect of turbulence and flame instabilities. Flame instabilities, and concretely Acoustic-Parametric instability, are treated firstly analytically identifying the regions of stability. In a secondary step the results of the theoretical investigation are utilized to model the phenomena in the simulations. A basic model that has been already utilized in productive calculations is presented. This model can be improved through the research of the process producing the flame wrinkling. This is carried out though the analysis of the Shivasinsky equation that helps to postulate an improved methodology.

We’ll be projecting video in room 1172, with some people remaining for a subsequent interview. Since 1172 only holds 10-11 people, and we have 5-6 interviewers already attending, we would appreciate an RSVP if you plan to attend in room 1172 (rather than via BlueJeans on your own computer in your office or elsewhere).

Please respond back to Tim Williams (zippy@anl.gov) and Joan Stover (jstover@alcf.anl.gov) if you plan to attend in conference room 1172.
