Turbulence measurements in a grid mixing tank
Meccanica, 1986An experiment is described in which a laser-Doppler anemometer was used to measure the spatial decay of turbulence generated by a vertically oscillating grid. In addition to being of theoretical interest, these measurements are necessary for scaling results from mixed-layer entrainment experiments.

Mixing and Flow in Glass Tanks
Journal of the American Ceramic Society, 1959Mixing influences that are effective during the flow of glass through continuous tanks are classified. Common experimental techniques for evaluating these influences are compared. A multi cell model is used to describe flow behavior in the absence of miring from transfer flow.

Analysis of turbulence anisotropy in a mixing tank
Chemical Engineering Science, 2006The objective of this paper is to analyze the gap between the local turbulence and the 3D isotropic state in a mixing tank stirred with a Rushton turbine. Experiments were carried out using the PIV technique, and phase average treatment permits the calculation of the six components of the Reynolds stress tensor. In order to quantify the gap between the

OPTIMUM MIXING TANK HEAD REGULATION
Mechanical Systems and Signal Processing, 2003Abstract The regulation of a connected tank system which is used for mixing dyes, in aqueous solution, is considered. Novel modelling, in matrix impedance (P,Q,R) form, from which the state space and transfer function, admittance, realisations of the system are generated, is proposed.

MIXING TIME IN UNBAFFLED STIRRED TANKS
2012Unbaffled stirred tanks, despite their poorer mixing performance with respect to baffled vessels, are gaining a growing industrial interest as they provide significant advantages in selected applications, including a number of biochemical, food and pharmaceutical processes.

CFD modelling and mixing in stirred tanks
Chemical Engineering Science, 1999In order to develop rational design procedures for stirred vessels, several important points have to be addressed. Firstly, it is necessary to relate the impeller-vessel geometry to the flow field produced. Secondly, it is necessary to establish energy balance in stirred vessels. Thirdly, it is necessary to understand the linkage between the flow field

Viscoplastic fluid mixing in a rotating tank
Chemical Engineering Science, 2007The laminar 2D mixing of viscoplastic fluids with an anchor impeller in a stirring tank is studied numerically. The flow structures, and particularly the static and moving rigid zones induced by the plasticity such as the presence of vortices, are examined in detail. Calculations are made for a wide range of yield and inertia values.

Forced plumes and mixing of liquids in tanks
Journal of Fluid Mechanics, 1975We consider the mixing between two miscible liquids of slightly different density (< 10%) when one of them (cargo) is injected into a tank partially filled with the other (inventory). The injection of the cargo is such that buoyancy and inertia act in concert on the plume produced by the cargo.
