This paper compares various methods which have been used for the estimation of turbulent
length scales, and/or the rate of dissipation of turbulence kinetic energy (ε) in stirred tanks …

The impeller discharge stream and bulk circulation flow produced by a pitched blade turbine
(PBT) in a fully baffled stirred tank have been defined, using a combination of flow …

In this work, the effect of scale on the macroinstability is examined using data from a 1.22 m
diameter tank. In a previous study coherent macroinstabilities (MI) in a stirred tank agitated …

In this paper a quantitative measure of errors introduced in the turbulent velocity RMS signal
due to the presence of macroinstabilities (MI) in the velocity field is presented. The velocity …

The stability of circulation patterns in stirred tanks was examined using tuft flow visualization.
Tufts were placed throughout the tank and their direction was recorded continuously for 20 …

Circulation pattern macroinstabilities and precessing vortices are known to exist in stirred
tanks, but until recently they have eluded a full quantitative analysis. In this article, frequency …

The complexity of flow in an agitated tank comes in part from the global change of flow
pattern from one type to another alternately on a long time scale. This phenomenon is …

抄録 Unstable flow phenomena in a mixing vessel with a marine propeller were investigated
experimentally using flow visualization and LDV techniques. It was found that the …

The flow pattern inside a scraped surface plate heat exchanger used for ice slurry
production is studied both experimentally and numerically. Isothermal planar velocity fields …

The purpose of the present study is to observe the effect of the blade attack angle on the roll
and trailing vortex structures in a stirred vessel via laser-Doppler velocimetry (LDV). In this …
