Quantities that need to be measured in gas fluidized-bed systems include solids volume
concentrations, solids velocities and solids mass flows, the vertical and horizontal …

We analyze here an experimental method for the evaluation of Umf in gas fluidized beds,
based on pressure fluctuation measurements in which Umf is determined by the relationship …

Gas–solid fluidization is a well-established technique to suspend or transport particles and
has been applied in a variety of industrial processes. Nevertheless, our knowledge of …

It is long known already that the pressure probe–transducer systems applied in gas–solid
fluidized beds can distort the measured pressure fluctuations. Several rules of thumb have …

In gas-solid fluidized beds, the distribution of the particles typically varies both in time and
space. Since the gas-solids distribution and its variation have a strong influence on the …

Fiber optic probes were used to measure local instantaneous solids concentrations and
local solids velocities inside a 0.4 m diameter bed. The velocity information was obtained …

ABSTRACT A laboratory scale circulating fluidized bed, 41 mm ID and 6.4 m high, has been
operated at fixed total solids inventory and variable superficial gas velocity (5 and 7 m/s) and …

Gas-solid fluidized-bed systems offer great advantages in terms of chemical reaction
efficiency and temperature control where other chemical reactor designs fall short. For this …

A state-of-the-art review of experimental methods for studying the hydrodynamics of gas-
solids fluidization is presented. Techniques applied by various investigators to obtain …

This paper reviews procedures for investigating the fluid-dynamic behavior of gas–solid
fluidized beds using pressure signals as obtained from modeling or experiments. The …
