This study develops a general discrete flow model which is
discrete both in time and space. A stirred tank network model
(continuous time compartment model) is summarized and then compared
with the discrete flow model. Both models make use of a
fractional input matrix with elements representing the fraction of...
The residence time distribution in a tubular flow vessel with
multiple baffles has been investigated. Length of sections between
the baffles, orifice diameter to vessel diameter ratio, and the flow
rates were varied, with the flow always in the laminar regime.
Conductivity measurements, involving tracer impulse response,
were used to...
Two new methods for the determination of solids movement in a fluidized bed have been developed and evaluated in this work. The first method used a deflecting plexiglass rod with strain gages attached to the base which is immersed in the bed of fluidized solids. The probe will yield a...
Elutriation of silica sand particles from a 0.9 X 0.9 m cold
fluidized bed was studied. Data were collected for cases with and
without tubes. During experiments the position of the tube bundle
above the distributor plate and the superficial velocity were varied.
Runs were made at velocities of 0.9...
Gas mixing is studied in fluidized beds of large particles. The
bed is 0. 483 m by 0. 127 m (19 in. by 5 in. ) in cross section and has
transparent plexiglass panels on the front and back. A tube matrix
made of twenty-seven 50.8 mm (2 in.) diameter...
