Multidimensional heat, mass and flow phenomena in gas stirred reactors

Abstract

Abstract Computations are presented for multi‐dimensional flows in gas‐stirred liquids contained in vertical cylindrical vessels. Mass, momentum, energy and concentration equations were solved for the buoyancy driven transient flows under investigation. Turbulence was simultated by using zero order and differential models of turbulence. The use of convective and diffusive time scales was analyzed. Reasonable agreement with available experimental data was observed.
