Equation 6.52 enables the net increase in volume of a bubble to be calculated. The bubble grows because more gas enters through the base than leaves through the cap. By injecting bubbles of carbon dioxide, which is not adsorbed by the particles, and analysing the concentration in the continuous phase at various heights in the bed, it has been... 

Porous or sintered plates are the ideal and are used in small-scale studies of fluidized bed behaviour (Kunii and Levenspiel, 1991) and form a highly expanded unstable gas-solid dispersion directly above the distributor which rapidly divides into a large number of small bubbles plus an emulsion phase. Bubbles grow rapidly thereafter by coalescence. Kunii and Levenspiel (1991) also suggest that other... 

As the superficial gas velocity increases, the nature of fhe bubbles changes. Especially in beds of small diameter or in deep beds, i.e. those with a bed depth to diameter ratio greater than unity, and with fine particles, the bubbles grow to the size of the bed container and push plugs of maferial up the bed as they rise. The particles then stream past... 

Bubbles grow large. Bed internals help keep bubble size down.

Beer and champagne bubbles are usually smaller than 1 mm in radius and are hence spherical. Because a beer bubble grows as it rises, the growth is controlled by convective CO2 transport into the bubble. With theories developed in Section 4.2.5.3, both the ascent velocity U and growth rate u of a single bubble in an infinite reservoir of beer or champagne can be calculated. The two must be calculated together because bubble size affects the ascent velocity, which in turn... 

The starting point for the Forster-Zuber theory (F4, F5, F6) is the Rayleigh equation (Rl) for a bubble growing in a liquid medium. In this...
