Predicting bulk powder flow dynamics in a continuous mixer operating in transitory regimes

Abstract: OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. This is an author-deposited version published in : http://oatao.univ-toulouse.fr/ Eprints ID : 9970 a b s t r a c tOver recent years there has been increasing interest in continuous powder mixing processes, due mainly to the development of on-line measurement techniques. However, our understanding of these processes remains limited, particularly with regard to their flow… Show more

“…Blenders have been modeled with a variety of approaches, including DEM simulations, population balance models, hybrid models combining DEM and PBM, Markov chain models, and residence time distribution models . Adam et al proposed an integrated quality‐by‐design (QbD) approach toward the design space definition of a blending unit operation with DEM.…”

“…However, none of the above-mentioned studies have been dealing with the transitory dynamics of such technological systems, despite of their industrial significance. In our previous recent works [22,23], we investigated the transitory dynamics of bulk solids flow in a Gericke GCM500 continuous mixer, using single powders (no mixture). The transitory phases that correspond to mixer start, emptying, as well as step changes in inflow rates or rotational speeds, have been studied in terms of outflow rate and hold-up weight variations.…”
