POSTER PRESENTATION
Poster_Krishna.pdfDevelopment of large eddy simulations of reactive flow using Eulerian stochastic field method coupled with tabulated chemistry. A solver named HybridESFFoam is currently developed. It is currently validated against Sandia Flame series.
Large Eddy Simulations of turbulent piloted methane jet flame Sandia DÂ & F using transported filtered density function (FDF) for turbulence-chemistry interaction. The transported FDF is solved stochastically using the Eulerian stochastic field method. The contour of temperature for both Flame D and F is shown below. A solver named ESFFoam has been developed.
Figure: Instantaneous snapshots of Temperature for Flame D (left) and Flame F (right)
From the above contours we can observe local extinction is observed for Flame F and almost no extinction is observed for Flame D. Low extinction is observed near the jet entrance for both Flame D and Flame F because of the stabilization provided by the pilot gas.
