Dispersion and Mass Transfer Coefficients in Fluidized Beds: Experimental and Computational Fluid Dynamics Studies,Used
Delivery time: 8-12 business days (International)
This study covers three Geldart groups, and includes stateoftheart experimental measurements and firstprinciples prediction The authors solved a longstanding problem in fluidization, namely extremely low Sherwood number of fine particles in fluidized beds The authors showed that the wellknown coreannulus profile reverses in slugging fluidization of Geldart D particles due to particle inertia effects This new finding is a robust and important one since coreannulus behavior is not desired These contributions to the field of particle technology are of high impact, and expected to be of lasting influence Christine Hrenya, Professor of Chemical and Biological Engineering, University of Colorado at Boulder. The authors have shown that we can eliminate the coreannular regime in risers By directly computing the mass transfer coefficients, the need to include empirical parameters could be eliminated to obtain more accurate conversion ratesReza Mostofi, Ph.D., UOP, A Honeywell Company.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
