چکیده
This paper provides an overview of existing technologies to measure flow parameters, such as material velocity and material concentration, in industrial transportation processes of particulate and powdery solids with a focus on pneumatic conveying. Restrictions, advantages and drawbacks of state of the art measurement principles are discussed. We show that capacitance-based sensing with suitable electrode topology allows for non-invasive, low-cost determination of flow parameters. Two industrial applications for material transportation by means of pneumatic conveying and of screw conveyors -

Measurement of Velocity and Mass Flow of Powders
− In this paper a cost-effective method for measuring transportation velocity and the velocity profile of a material flow of powdery solids inside a pipe is presented. For the measurement, artificial perturbations are brought into the mass flow and the effects of these perturbations are acquired and correlated at measurement sections. The velocity profile is calculated with the knowledge of the...

متن کاملLaminar mixing of high-viscous fluids by a cylindrical chaotic mixer
Laminar mixing of glycerin in a chaotic mixer is carried by means of the blob deformation method. The mixer was a cylindrical vessel with two rotational blades which move along two different circular paths with a stepwise motion protocol. The flow visualization was performed by marking of the free surface of the flow with a tracer. The effects of controlling parameters such as rotational speed ...
