Analysis of annulus flow behavior of Geldart Group B particles in a CFB riser Larger particle diameter dictated upflow annulus behavior in monodisperse systems. Binary mixtures largely showed upflow annulus behavior. Impact of polydispersity pronounced at lower solids loadings Applicability of available riser flow regime maps limited for Geldart Group B
