We propose a new concept of knowledge management “Knowledge Liquidization and Crystallization”, and a system “Knowledge Nebula Crystallizer” to support the process. Though there are several theories about knowledge creation (Nonaka et al. 1995)(Fischer et al. 2001)(Shneiderman 1998) and a number of companies have realized their importance, most of them face to difficulty of applying them to the...

A simplified, systematic approach to the mathematical simulation of crystallizers is attempted by using the fundamental principles of mass conservation, via a population balance to the solid phase and a solute balance to both solid and liquid phases. A continuous, isothermal and isochoric crystallizer is assumed to be described by the MSMPR model under transient operating conditions with comple...

In order to improve the traditional freezing crystallization process of calcium nitrate in nitric phosphate process, crystal growth experiments by adding Ca(NO3)2·4H2O seeds in supersaturated calcium nitrate solution in a Circulating Fluidized Bed (CFB) crystallizer were carried out on crystal growth kinetics. The results showed that the growth of C...

In this publication, the issues of computer simulation electromagnetic and hydrodynamic processes in an crystallizer mold a silicon melt periodic action are considered. The crystallization process proceeds under conditions additional heating by eddy currents melt. main task interaction inductor field is to create repulsive force exclude mechanical contact between lining surface. When problem so...

The development and production of new aluminum-based materials is a critical task the up-to-date industry. Particularly, are necessary to produce light, strong, thermally-stable wires cables for household usage, transport, power sphere. paper presents results study microstructure physical mechanical properties Al–0.5Fe Al–1.7Fe alloys (wt. %), produced by continuous casting into an electromagne...
