“…(5) (6) However, the above "Solid Scattering" model takes no account of the unique properties of "flocs" (large aggregates formed by polymer flocculation), in terms of the interaction of sound with the bound fluid. In order to model flocculated particle acoustic parameters from unflocculated primary particles to large, lowdensity flocs, Thorne et al 23 detailed a "Hybrid" model to take account of both fluid and solid properties.…”

“…The development of novel techniques to characterize the waste particle size and concentration in such hazardous environments is, therefore, imperative to allow for efficient and safe processing operations. Acoustic devices represent a promising technique, as they are used extensively to measure sediment transport in estuarine environments and, by appropriate adjustment of frequency range, size, and concentration, can also be utilized nondestructively and nonintrusively. , In nuclear applications, ultrasonics have been used for in situ bed profiling , and nondestructive testing but have not been applied for concentration measurements. More generally, ultrasonics are increasingly a critical technique for the in-process evaluation of multiphase mixing and transfer systems in a variety of industries. , …”

This study investigated the performance of an acoustic backscatter system (ABS) for the in situ particle characterization of complex wastes. Two sediments were used: a fine, milled calcite that was flocculated with anionic polyacrylamide and naturally flocculated pond sludge. Particles were initially measured independently by light-based techniques to gain size, the coefficient of variation (COV), and fractal dimensions. For acoustic experiments, a bespoke, high-fidelity ABS was employed with 1, 2.25, and 5 MHz probes and a recirculating mixing tank. Initially, the concentration independent attenuation and backscatter coefficients were measured for each system using a robust calibration procedure at multiple concentrations. Comparisons of the total scattering cross-section (χ) and form function (f) were made between the experimental data and two semiempirical models: a Solid Scattering model and a Hybrid model (where the effects of bound fluid are incorporated). Experimental data compared more closely to the Solid Scattering model, as it was assumed scattering was dominated by small, bound “flocculi” rather than the macroscopic structure. However, if the COV was used as a fit parameter, the hybrid model could give equally accurate fits for a range of input aggregate sizes, highlighting that important size and structure information can be gained from the acoustic models if there is some a priori system data. Additionally, dual-frequency inversions were undertaken to measure concentration profiles for various frequency pairs. Here, the lowest frequency pair gave the best performance (with accurate measurements in the range of 2–35 g·L–1) as interparticle scattering was lowest.

We propose a method for estimating volume fraction of emulsions based on ultrasonic velocity profiling viscometry and validate its feasibility through a series of experiments. The experiments involve emulsions composed of silicone oil as continuous phase and tap water with volume fractions ranging from 10vol% to 30vol%. We introduce the viscosity model for this emulsion to establish the mathematical relationship between volume fraction and viscosity. Subsequently, we calibrate this relationship using ultrasonic spinning rheometry (USR). The identified equation is then applied in estimating the inline volume fraction using ultrasonic velocity profiling combined with pressure drop measurement. The key idea is that by measuring the viscosity in a pipeline the volume fraction is then indirectly estimated employing the identified equation. Through the collection and analysis of experimental data, we confirmed that the USR can capture the characteristics of the emulsion viscosity accurately. Moreover, we found that this method demonstrates applicability and accuracy in measuring volume fractions of emulsions. The results indicate that the mean relative error for this estimation is 24.06% at a volume fraction of 10vol%, and 4.78% at a volume fraction of 30vol%.
