✦ Synopsis

Bubble size and nsmg velocity m freely bubblmg hqmd%as and three phase fhudrzed beds have been measured by means of movie photography Three sohds (l-6 mm), a variety of hqtuds, and au were employed as the three phases Both bubble Size and rlsmg velocity were found to Increase with gas velocity but were relatively InsensItIve to the hqtud velocity, vacoslty, and surface tensIon At the high gas rates employed, the bubble charactenstlcs were independent of parkle size Correlations are presented for calculatmg bubble size and nsmg velocity
