Fluid Flow and Gas Dispersion in Stirred Tank Reactors

摘要

Fluid flows, heat transfer, and dispersion of gas in stirred tank reactors was studied. Dead zone formation of the used pseudoplastic slurries was examined theoretically and experimentally to discover a suitable scale up method for these reactors. The theoretical calculations are based on theories of maximum gas flow in stirred tank reactors, and on Kolmogoroff's theories on length and velocity scales of turbulence. A method was developed for estimation of the reactor response by means of matrices. With this model the response of 8(t)-pulse or step response for both batch and continuous system can be calculated.
