Turbulent impellers are classified as axial or radial flow impellers. Axial flow impellers cause the tank fluid to flow parallel to the impeller’s rotation axis. Radial flow impellers cause the tank fluid to mixing of fluids 6File Size: 1MB.

Liquid-liquid dispersions in stirred vessels or mixers are often used technical applications in the chemical, pharmaceutical, mining, petroleum and food industry. For controlling and optimizing these systems exact knowledge about the drop size distribution and its transient behavior under changes of energy input, temperature or composition is.

These different surfaces include clean gas-liquid surfaces, clean liquid-liquid interfaces, and film-covered surfaces. The last few chapters focus on the more detailed discussion on turbulence, such as the concept of spontaneous interfacial turbulence and Book Edition: 1. A dispersion is a system in which distributed particles of one material are dispersed in a continuous phase of another material. The two phases may be in the same or different states of matter.. Dispersions are classified in a number of different ways, including how large the particles are in relation to the particles of the continuous phase, whether or not precipitation occurs, and the.

The flow of two immiscible liquids presents a wide variety of flow patterns ranging from relatively quiescent stratified flow to regimes in which intense mixing between the phases occurs. The more recent studies are illustrated in Figure 1 [Arirachakaran et al.
()]. As suggested by this figure the nature of liquid-liquid flows is highly complex, with full stratification occurring at low. Abstract: We study liquid-liquid dispersions in a turbulent Taylor - Couette flow, produced between two counterrotating coaxial cylinders. In pure Water and in counterrotation, Reynolds numbers up to 10^5 are reached.
We first characterize the single-phase flow, in terms of threshold for transition to turbulence, scaling of the torque and measurements of the mean flow and of the Reynolds Author: Florent Ravelet, Rene Delfos, Jerry Westerweel.

Liquid-liquid dispersions in a turbulent flow are common in many applications in chemical, petroleum, pharmaceutical, and food industries. Processes involving liquid-liquid dispersions include suspension polymerization, extraction, and heterogeneous reactions. The rate of a heterogeneous chemical reaction is often controlled by mass by: 1.
This paper presents an experimental study of pressure drop of single-phase flow and liquid−liquid dispersion through a Sulzer SMX mixer in the turbulent flow regime. Emulsification experiments are performed with various numbers of mixing elements from 2 to 20 and different flow rates ranging from to L/h.
Pressure drop in single phase flow when Re is greater than is modeled using Cited by:. Dispersions are produced by high shear mixing devices that impart a high level of turbulent energy to the system.
This energy appears as turbulence which produces droplets of one of the liquids which is “dispersed” into the other. The emulsification process in a static mixer HEV (high-efficiency vortex) in turbulent flow is investigated. This new type of mixer generates coherent large-scale structures, enhancing momentum transfer in the bulk flow and hence providing favorable conditions for phase by: The AIChE Journal is the premier research monthly in chemical engineering and related fields.
