TL;DR: In this paper, a pitch-catch method is adopted to model the measurement system where two PZT wafers are mounted on upper and lower surface of the plate to act as actuators to transmit the desired Lamb wave mode (S0 or A0).

TL;DR: In this article, a model based on the conservation of mass in a slug provided a relationship between slug velocity terms, length, porosity and the stationary layers, for constant slug length conditions the new model was shown to be equivalent to the gas-liquid analogy model of Konrad.

TL;DR: In this article, the authors used the vast data available in the literature, which is representative of the entire mode of flow, and relates the stationary layer and slug velocity to predict the two constants from only these inputs.

TL;DR: In this paper, the amount of particle deposition in the horizontal pipeline after a conveying was calculated by controlling the solids feeding rate using a rotary valve and by monitoring the solid flow out of the system using dynamic load cells.
Abstract: Solids deposition in the horizontal pipeline of a pneumatic conveying system was studied both mathematically and experimentally. Mathematically modelled results using the coupled discrete element method (DEM) and computational fluid dynamics (CFD) approach have demonstrated an intensive exchange of particles between the stationary layer (deposited particles) and the moving slug and a variation of solids concentration and pressure and velocity distributions across the slug. Slug flows were also visualised experimentally through a glass section and analysed by a high-speed video camera. The amount of particle deposition in the pipeline after a conveying was calculated by controlling the solids feeding rate using a rotary valve and by monitoring the solids flow out of the system using dynamic load cells. Experimentally generated data have quantitatively shown a tendency of more solids deposition with lower gas mass flow rate in slug flows except that, below a certain amount of solids mass flow rate, the deposition becomes independent of gas flow rate.
