Fluidization and Fluid-Particle Systems Research Needs and Priorities. Proceedings of the NSF Workshop Held at Rensselaer Polytechnic Institute, Troy, New York on October 17, 18, 19, 1979

摘要

The workshop brought together researchers in fluidization and fluid-particle systems from industry, government, and academic institutions to discuss research needs and priorities. Participants reviewed the many large and small scale fluidized bed processes presently in use and/or under development and studied their applications to energy and the environment. They also reviewed fluid-particle systems such as those used in pneumatic transport, standpipe flow, and spouting. Much attention focused on a presentation of large scale facilities and scaleup since phenomena such as bubble size, size distribution, and particle circulation are scale dependent. The need for large scale research facilities was noted. Also raised was the fact that dynamic models for fluidized beds are non-existent, as is the case for spouted beds, and other fluid-particle systems. Other papers discussed equations of motion, stability, heat and mass transfer, chemical reaction, elutriation, attrition, mechanics in the distributor plate and freeboard regions of fluidized beds, effects of electric and magnetic fields, and the turbulent fluidization of large particles. Many graphs, illustrations, and bibliographic references highlight the report.
