Popis: Experimental data on the true gas void fraction in a vertical tube under the bubbling flow regime are presented. A generalization of these data on the basis of the drift flow model of Zuber with the distribution parameter C 0 = 1.2 and the weighted average gas velocity u 2j = 0.16 m/s is given. The results of assessing the parameters of the downcoming flow of the fluid in the near wall zone are shown.
