Research output: Chapter in Book/Conference proceedingConference contributionpeer-review


A study on developing correlations for better prediction of solids holdups in the fully developed region of cocurrent upflow and downflow two-phase flow was carried out. The solids concentration in the fully developed zone of CFB risers and downers was experimentally investigated by measuring axial pressure gradients profiles in two CFB risers. The predicted values by the proposed correlation agreed well with experimental and published. This is an abstract of a paper presented at the 2006 AIChE Annual Meeting (San Francisco, CA 11/12-17/2006).
