The usefulness of phenomenological tools to simulate the consequences of dust explosions

Abstract : Using numerical modelling is a "natural" step in today's engineering work, even in safety. Up to a certain extent, solving more or less accurately the basic Navier-stokes equations has replaced the traditional analytical approximate solutions of the same equations. Doing this, we surely have gained in flexibility, sometimes in accuracy, but we may have lost in expertise and ergonomics. In this paper, different modelling ways are set in perspective for the specific case of explosions, trying to link them to a specific area. It is the opinion of the present authors that simple physical "modelling" is justified in areas where a consensus is required on "basic " approaches as for standards, that complex numerical modelling is particularly fruitful in research and that some intermediate "phenomenological" modelling is possible and proves profitable for process safety where some technical expertise is required. Example of such tools are given and compared to existing data.
