Numerical study of circle fractal grid perforated plate as a turbulent generator in combustion chamber
Fractal grids can be used to design turbulent flows with low power losses and high turbulence intensities for intense yet economic mixing over a region of designed length and location.

| Summary: | Fractal grids can be used to design turbulent flows with low power losses and high
turbulence intensities for intense yet economic mixing over a region of designed length and
location. The introducing circle grid perforated plate is the main aim of this present paper. In this
numerical work, we want to ascertain a new approach in turbulence generators on the structure of
premixes flames using perforated plate fractal-grids pattern. In this paper, we compared circle grid
perforated plate by varies using its diameters, spacing and number of holes on the plate. The result
showed good perceptivity of the fractal generated turbulence and the fractal flow physics. The
turbulent intensity can be increased by a grid with higher blockage ratio. |
