Experimental determination of the mixing requirements for solid suspension in pharmaceutical stirred tank reactors
… speed, N_{js}, to just suspend finely divided solids. In this work, N_{js} was experimentally obtained for a number of different pharmaceutically-relevant agitation systems including vessels with different types of bottoms (torispherical or hemispherical), impeller types (RBI, disk turbine, …

Minimum agitation speed for solid suspension and mixing time in a torispherical -bottomed pharmaceutical stirred tank under different baffling conditions
… agitation speed, NS, required to just suspend solid particles dispersed in water was experimentally determined in this work for a glass-lined type of mixing tank provided with a torispherical bottom and agitated with a retreat-blade impeller under different baffling configurations. Ns for the …

Particle Diffusivity in Fully Developed Turbulent Pipe Flow of Dilute Suspensions
… turbulent horizontal pipe flow of dilute air-solid suspension under the influence of gravity and electrostatic forces.

Measurement of properties of gas-solid suspensions using phase-Doppler anemometry
… flow properties of a dense turbulent air-solid suspension in a horizontal pipe was undertaken. The flow properties were measured along vertical and horizontal diameters using Phase Doppler Anemometry which was a nonintrusive technique that measured the size and velocity of particles within …

Dynamic behavior of unsteady turbulent motion in pipe flows of dense gas-solid suspensions
Unsteady stratified motions in dense gas-solid suspension in horizontal pipe flows at low velocities have been observed, but the means for predicting these motions are lacking. For a dense suspension, the effects of particle-particle interaction, the damping of fluid motion by particles and the …

The measurement of the velocities of particles in an air-solid flow
… for particle velocity measurements in air-solid flows. The aim of the investigation was to find the range for which the LDV was suitable, and also to make useful measurements in a pipe conveying a dilute suspension of solids pneumatically. Air and solid velocity distributions across the …

Coordination Cages as a Scaffold for Permanently Porous Liquids
… property that is conventionally associated with solids. While liquids can have transient pores, these cavities exist as temporary voids between the molecules of the liquid. The idea of permanently porous liquids combines the porosity of solids with the fluid properties of liquids by engineering …

Single and multiphase mixing in partially filled stirred vessels
… achieved, both in a single liquid phase and in solid-liquid suspensions. Flat-bottomed, baffled vessels (5L, 12L, 20L and 170L) equipped with a single disk turbine (DT) of four different sizes placed at five different impeller off-bottom clearances were used here to study the system's …

The application of laser measurement techniques to the pneumatic transport of fine particles
… and hence, to the velocity of the fluid. When solid particles are conveyed pneumatically, for example in transport chemical reactors, in drag reducing flows, and in certain heat transfer processes, the particles are generally much larger than the usual seeding particles, and thus do not travel …

Experimental determination of solids suspension with angled impeller in a pharmaceutical mixing vessel
… is that they are capable of suspending small solids dispersed in the liquid. Therefore, it is critical to know the value of the minimum agitation speed at which solids become just suspended,N_{js}. Despite their common use in industry, and especially the pharmaceutical industry, these systems …

Injection Impairment by Suspended Solids: Well Models, Filtration Parameters, and Models’ Validation with 3-D Injection Experiments
… loss of injectivity. Water injection, without solids suspension, at high velocity generates a loss of injectivity as a non-Darcy flow effect. The compounding impacts of high injection fluid velocity with suspended solids are expected to produce more severe injectivity loss than water alone. The …

Development of Micro to Milli-Scale Multiphase Reactors with and Without Solids for Integration Into Mini-Monoplants
… wt% H₂SO₄ (aq) were used as the fluid. Then, the solid suspension handling of a baffleless oscillatory flow coil reactor is characterized through two solid forming reactions, with the first being a model precipitation reaction and the second being a more mixing intensive phase transfer catalysis …

Hydrodynamics, dissolution, and mass transfer effects in different dissolution testing apparatuses and laboratory systems
… modeling approaches to study mass transfer and solid suspension effects. The issues that were investigated depended on the specific apparatus. For the case of the USP Dissolution Testing Apparatus 2, the effects of the presence of different probes on the hydrodynamics in the dissolution vessel …
