Turbulent Combustion

For my PhD thesis, and subsequent year as Post Doc at the University of Sydney, Australia, I worked mostly with the Conditional Moment Closure (CMC), a state-of-the-art model that is used to capture turbulence-chemistry interactions (e.g., [1], [2]). From 2005-2006 I had the great honour of working with Prof. Robert W. Bilger as a Post Doctoral research fellow at the University of Sydney, Australia. In Sydney I worked on CMC for spray combustion [3] and a version of my consistent turbulent mixer model [4] that I have called the presumed mapping function approach [5] [6]. The presumed mapping functions have been implemented in the open source package PMFpack, available under a GNU Lesser General Public License. My work on CMC led to several papers in collaboration with Prof. Steve de Bruyn Kops, using very large Direct Numerical Simulations to validate turbulence-chemistry models [7], [8], [9].
