“…In simulations, the corresponding prevention of loss of solids from the top of the column was achieved by specifying a very tall domain which allowed the solids to fall back down. Though the experiments were conducted in the presence of acrylic bounding walls (pseudo‐2D arrangement), the development of self‐similar velocity profiles for both phases inside the jet plume has been consistent with the analytical Gaussian profile for two‐dimensional jets . Therefore, the simulations conducted in this article were two‐dimensional and the governing equations were not solved along the thickness direction.…”

A continuum gas–solid model that includes descriptions for solid frictional stress and a turbulent gas phase is evaluated against published experimental measurements of mean and fluctuating velocity inside the jet plume region of a bubbling fluidized bed with a high‐speed vertical jet injection. The main uncertainties in closure relations necessary in the continuum model are first identified and then determined using available experimental data. The overall model shows good agreement with both the gas and particle experimental velocity profiles. The trends in the centerline mean and fluctuating velocity with change in the fluidized state of the emulsion are also captured favorably. Main deviations between the model and experiment are noted and possible reasons for the mismatch are discussed. © 2013 American Institute of Chemical Engineers AIChE J, 59: 3247–3264, 2013
