- Characteristics of PMMA dust combustion under turbulence field
抄録
The purpose of this study was to investigate the influence of flammable dust flames under an isotropic turbulence field. Polymethyl methacrylate powder which has a spherical shape and narrow size distribution was used as a fuel. Aflame of the PMMA powder was formed in a cylindrical combustion chamber with 8-L of volume in which the isotropic turbulence field was produced by moving a holed flat plate. The turbulence intensity in the chamber was preliminarily estimated by a wind tunnel experiment. The smaller amounts of powder were more affected by the increase of turbulence intensity. As the particle size increased, the maximum pressure decreased and the flame front was thicker. The particle size more than 30 µm was greatly affected by convective heat, and the maximum pressure increased with the increase of turbulence intensity.
