Normal 0 false false false MicrosoftInternetExplorer4 Our research addressed double diffusive interface instabilities of autocatalytic chemical planar fronts and axisymmetric plumes observed in the iodate-arsenous acid reaction. The study of autocatalytic buoyant plumes and flame balls is done in collaboration with Prof. S. W. Morris and Mr. M. C. Rogers, Department of Physics, University of Toronto who performed the original experiments. Navier-Stokes solvers in cylindrical geometry that run on a single processor or on a cluster under MPI were developed. The TOC and Nugget are for a weakly buoyant situation with RT=0.1, RC=0.17, Sc=9000 and Le=280, and were presented at the 2008 Gordon Conference on Oscillations & Dynamic Instabilities in Chemical Systems. Additional simulations are in progress and a journal article will be written.Linear theory for the instability of a plane chemical front in a continuous fluid is complete. We are currently studying subsequent nonlinear interface break up. A journal paper that describes both the linear theory and nonlinear dynamics will be written.
