The effect of axial height on flow development was not obvious in fully developed region under the same operating condition. Superficial gas velocity and solid circulating rate had significant influence on particle velocity in the center region of the riser. Besides, comparisons among rising, descending and average particle velocity were conducted. The particle average velocity was similar to the rising particle velocity and higher than the descending particle velocity in radial locations except the wall region of riser.}, journal = {International Journal of Chemical and Molecular Engineering}, volume = {9}, number = {7}, year = {2015}, pages = {829 - 833}, ee = {https://publications.waset.org/pdf/10001835}, url = {https://publications.waset.org/vol/103}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 103, 2015}, }
