Abstract
An improved bubble velocity equation is developed for gas‐solid fluidized beds. Model parameters are evaluated from reported experimental results of bubble flow. Finally, this improved equation is compared to the commonly applied velocity relationship of Davidson and Harrison (1963).Keywords
