Current Research Work

Martha Salcudean’s research group is working on the mathematical modeling of multi-phase flows. The current emphasis in on simulation of flow and associated mass and heat transfer in fluidized beds, used extensively in chemical, pharmaceutical and other industries. Gas-solid –liquid flows, which occuroften in fluidized beds are modeled by solving the governing differential equations with numerical methods, using Eulerian-Eulerian, and Discrete Particle Methods. Nozzle performance is investigated and optimized by simulating the gas-liquid flow, in the gas assisted atomization nozzle and its interaction with the fluidized bed. Agglomerate formation often occurs in fluidized beds with liquid injection. That can be desirable in some processes, as for instance in pharmaceutical processes ,or highly undesirable, as for instance in the bitumen coking reactor. The research team is working on improving the understanding of the agglomerate formation, by modeling their growth and breakage in the presence of capillary and viscous forces, using population balance and Discrete Particle Methods.
