Title: Comparison Of The Heat Transfer In Helical Coils And Jacketed Stirred Tank Reactors
Author: Nunhez J.R.

Abstract: Despite its importance in the chemical industry, the design of stirred tank reactors (STR) still essentially relies on empirical methods. No account is taken of the dynamics of the system and uniform mixing and concentrations are assumed throughout the vessel. These assumptions are patently not satisfied. Any improvement in design depends on a knowledge of the flow patterns, temperature distribution and concentration variations in the vessel. This work presents a computational study of how the flow patterns of a non-Newtonian viscous fluid are affected by different arrangements of internal and external heat transfer surfaces for: (a) jacketed vessels and (b) internal helical cooling coils where agitation is provided by a six-blade Rushton turbine impeller.
