Dust explosion is a constant threat to industries which deal with combustible powders such as pellets producers, food industry, metal industry and so on. The current standards regarding dust explosion venting protecting system are based on empirical correlations and neglecting complex geometry, which may lead to failure in estimating explosion overpressure and therefore risk for fatalities at workplaces. Therefore, there is an urgent need for a reliable tool for vent protection design in the process plants. The objectives of this presentation are (i) to implement a model that focuses on turbulent burning of a dust-air cloud in an open source platform OpenFOAM, (ii) to verify the implementations against analytical solutions for 1-D planar and 3-D spherical premixed turbulent flames and (iii) to validate the model against Leeds cornflour dust explosion vessel experiments.
