The effects of mass flow rate and subchannel configuration on
the turbulent interchange between adjacent subchannel in simulated
rod bundle were investigated.
The simulated rod bundle was made by arranging seven 1.913 cm
diameter acrylic plastic rods in an equilateral triangular pattern in a
tube 8.89 cm inside diameter.
The...
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...
The micro-based reactor can be considered as two phases: the main fluid and the gel phase. When the reactants p-chlorophenol enters reactor, diffuses from the main fluid to the gel phase. The diffusion and convention of p-chlorophenol happen in the main fluid. However, there is no convection in the gel...
Microscale reactors operate in sub millimeter space dimensions. Their small length scale enables process intensification of mass, heat and momentum transport that influence reaction rates. Hence it's possible to observe the true intrinsic reaction kinetics occurring for a set of reactions. In this work a novel microscale reactor for producing...
Microscale-based technology has potential applications in the medical field. The development of a new microscale medical device requires experimentation and testing. This can be done by creating a breadboard device that can perform the functionalities the final device should be able to do. This breadboard device can also be used...
In a conventional well-mixed fluidized bed the solids are almost
completely mixed and the residence time for individual particles may vary
between zero and infinity. For materials especially sensitive to the processing
time, a wide distribution of residence time is extremely undesirable. A multi-compartment
fluidized bed was proposed to minimize...
Production of dry particles made of titanium dioxide powder and black liquor is
the first step in a newly proposed black liquor treatment process (Frederick et. al., 1992).
This work investigates the granulation processes in a fluidized bed granulator of titanium
dioxide and black liquor. Experiments are performed in a...
