SIMULATION OF HYDRODYNAMICS AND HEAT TRANSFER OF A GRANULATED MEDIUM IN A CIRCULAR BUNKER

Numerical simulation of the hydrodynamics and heat transfer of a dense layer of a highly loose high-concentration granulated medium in a circular bunker on the basis of a non-Newtonian medium with application of the ″power-law liquid″ model and boundary slipping conditions on solid walls is presented. The infl uence of regime and geometric parameters on the dynamics and heat transfer of a high-concentration granulated medium is investigated. The validity of the results obtained is confi rmed by comparison of the numerical results with well-known experimental and analytical data. The results of the investigation carried out can be used in powder technology apparatuses in the processes of drying, mixing, homogenization, batching, and transportation of granulated materials.
