niriosrat is on a distinguished road
The study is focused on the development of a CFD model able to simulate the dispersion and combustion of Wheat Starch dust, following the 1226-12a testing protocol proposed by the American Society for Testing and Materials (ASTM). The CFD model is expected to correctly estimate explosivity parameters, such as maximum explosion pressure and maximum rate of pressure rise, as well as some characteristics of the reacting turbulent flow, such as the distribution of the chemical species throughout the geometry, the propagation of the flame, and the velocity of the gas/particle phases. Although the some simulations proposed showed appropriate convergence levels, some inconsistencies have been identified between the final mass of the dispersed phase and the final mole fractions of the continuous phase. A detailed description can be found in the attached document:
