The effect of fractal grid generated turbulence on the structure of premixed flames

Autor: Sponfeldner, Thomas

In this thesis fractal grids as a new type of turbulence generators for premixed combustion applications are investigated. Fractal grids produce turbulence fields which differ from those formed by regular turbulence grids such as perforated plates or

Thermo-acoustic instability can be caused by the feedback mechanism between unsteady heat release, acoustic oscillations and flow perturbations. In a gas turbine combustor limit cycles of pressure oscillations at elevated temperatures generated by th
