A detailed experimental characterization of the flow dynamics of a closely sized sample of cylindrical particles is reported here. Issues relevant to the design of reacting and nonreacting fluid-solid contacting devices, e.g., pressure drop behavior, fluidization behavior and settling behavior, both in Stokes law as well as the intermediate region, were investigated. The common approach of extending correlations meant for predicting the fluid dynamic parameters of spherical particles to nonspherical particles, with the help of the sphericity shape factor. such that particle diameter is the product of the equivalent volume diameter and the sphericity of the nonspherical particle, was examined here. Notwithstanding the simplicity of this approach, caution must be exercised as far as fluid dynamic parameters thus obtained are concerned. Significant error was observed here in all cases. However, improved predictions were obtained using available correlations whose parameters were optimized using a database of nonspherical particles.
