Discrete modeling of flow systems

Creator:: Chang, Feg-Wen
Abstract:: 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...

Residence time distribution in tubular flow vessels with multiple baffles

Creator:: Satvat, Behrooz
Abstract:: 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...

Measuring solids movement in a large particle, air fluidized bed : two new methods

Creator:: Donlevy, Byron Tristan
Abstract:: 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...

Gas flow in fluidized beds of large particles : experiments and theory

Creator:: Jovanovic, Goran N.
Abstract:: 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...

Solids movement in a tube-filled fluidized bed

Creator:: Deaton, William W.
Abstract:: Mixing of ferrite tracer with silica sand was studied in a 0.91 m x 0.91 m cold fluidized bed. Inductance probes located Inside dummy heat transfer tubes [in a 4 x 4 x 4 array] were used to monitor a ferrite tracer with physical properties similar to coal as it...

Fluid dynamics in a two dimensional fluidized bed of large particles

Creator:: Stephanakis, Adonis C.
Abstract:: Observation shows that bubbles in large particle fluidized beds behave quite differently from beds of fine particles. They expand and can grow faster than they rise. Bubbles in fine particle beds seem to grow primarily by coalescence, while in large particle beds they are observed to grow mainly without coalescence....

Dynamics and control of continuous crystallizers

Creator:: Leu, Lii-ping
Abstract:: The theoretical analysis of an unseeded, isothermal mixed-suspension mixed-product-removal (MSMPR) crystallizer with a fines trap is developed. The lumped parameter system equations are presented for a homogeneous nucleation and a number-dependent secondary-nucleation model. Linear stability analysis and system simulations are used to investigate the system's dynamic behavior. Modal control algorithms...
