Abstract Mixed particle systems are commonly employed in industrial processes, where the characterization of size parameters and mixing ratio can frequently serve as key indicators process control production optimization. A Monte Carlo (MC) model was developed to numerically predict study ultrasonic attenuation spectrum characteristics polymethyl methacrylate (PMMA)-glass aqueous suspension, together with swarm optimization (PSO) algorithm, handle inverse problem solving size, distribution...
Acoustic agglomeration proves promising for preconditioning fine particles (i.e., PM2.5) as it significantly improves the efficiency of conventional particulate removal devices. However, a good understanding mechanisms underlying acoustic in standing wave is largely lacking. In this study, model that accounts all important particle interactions, e.g., orthokinetic interaction, gravity sedimentation, Brownian diffusion, mutual radiation pressure effect and wake effect, developed to...
Accurate measurement of temperature and velocity fields in combustion flow diagnostic plays an important role analyzing the heat transfer mechanism ensuring safe operation equipment. In this work, considering refraction effect sound waves, are reconstructed simultaneously based on nonlinear acoustic tomography (NAT) by using covariance matrix adaptation evolution strategy (CMA-ES) algorithm. forward problem, fast two-point ray-tracing algorithm is introduced to track curved waves more...
Size characterization of nanoparticles has gained wide concerns in the past decades, but it remains a challenge for measurement suspensions up to now. The extremely small scales particle size result great difficulty traditional static light scattering method and optical imaging. In addition electron microscopy techniques, dynamic (DLS) is another widely used technique laboratory analysis samples. Moreover, ultrasonic attenuation spectroscopy (UAS) also being developed rapidly provide an...
In the characterization of particle size distribution (PSD) using ultrasonic attenuation method, spectrum characteristics such as bandwidth or number frequencies is great significance. To obtain desired spectra consisting sufficient information, a direct digital synthesis (DDS) based excitation method has been proposed burst superposed wave (BSW) featuring in to be freely defined and component waves' energy artificially controlled. Corresponding experimental systems are designed, which...
Interactions between fine particles (PM2.5) suspended in flue gas can be promoted via application of acoustic fields. This may lead to particle collision and agglomeration, thereby facilitating possible realization PM2.5 abatement. The dynamic behavior interactions standing wave fields, however, is not well understood, this severely restricts the development practical agglomeration devices. Availability limited information concerning interactions, insufficient consideration interaction...
In order to improve the applicability, spheroidal particles are substituted for spherical in traditional modeling of multi-wavelength light extinction method. The coefficient and spectrum calculated at different axial ratios under configuration generalized Lorenz-Mie theory. Combining with regularization inversion algorithm, influence particle shape on size characterization by method is discussed detail. That is, arithmetic statistical average stochastic incidence statistics employed...
