Turbulence & Combustion



By Dr Arnaud MURA

The course objectives are to be able to represent turbulent reactive flows (eventually multiphase) in order to perform numerical simulations with industrial or research codes. It is illustrated by numerous experimental visualizations (direct emission, tomography, PLIF, etc.) allowing to better assess the phenomenon. Applications of the main concepts are proposed.

  1. Presentation of the Equations for Aero thermo chemical flows (simplification at low Mach number, unitary Lewis number, derived variables: Schvab-Zeldovich, mixing fraction...)

  2. Laminar Flames Structure: diffusion, premixing, partial premixing. Mixing rate (scalar dissipation), relation to production rate.

  3. Turbulence (scales, spectral dynamics, DNS, RANS, LES), relation between Micromixing and PDF, Closure problem for the Reactive Scalar.
