Available in PDF, EPUB and Kindle. Book excerpt: Rapid, on-line characterization of the particle size and concentration of moderate to highly concentrated slurries is required for efficient waste remediation at the DOE complexes. This paper discusses the advancements achieved under the Environmental Management Science Program to accurately characterize high-level waste at the high concentrations expected at the DOE complexes. In addition, the results are applicable to efficient process measurement and control in many chemical and pharmaceutical manufacturing processes. Existing methods for determining the particle size and concentration of non-dilute slurries based on ultrasonic attenuation can become inaccurate due to the complex interactions of ultrasonic waves with the constituents of the slurries and the necessity for very careful transducer alignment. Two measurements that help to overcome these difficulties are the ultrasonic backscattering and diffuse field. The backscattering measurement is attractive because viscous, thermal and inertial effects have small contributions to the backscattering. In addition, the backscattering theories are simpler than attenuation theories and lend themselves to more stable inversion processes. Furthermore, the measurements of backscattering measurement do not require long travel distances and can be made with a single transducer thus eliminating alignment problems. We will present ultrasonic measurements and theoretical comparisons on solid liquid suspensions designed to elucidate the particle size and concentration at high concentration relevant to the high level waste at the DOE complexes.

Book excerpt: Using an ultrasonic field, properties of a solid liquid suspension such as through-transmission attenuation, backscattering, and diffuse field are measured. These properties are converted to quantities indicating the strength of different loss mechanisms (such as absorption, single scattering and multiple scattering) among particles in the suspension. Such separation of the loss mechanisms can allow for direct comparison of the attenuating effects of the mechanisms. These comparisons can also indicate a model most likely to accurately characterize the suspension and can aid in determination of properties such as particle size, concentration, and density of the suspension.

Download or read book Measuring the Absolute Concentration of Particles in Suspension Using High Frequency B mode Ultrasound Imaging written by John Haeseon Lee and published by . This book was released on 2016 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concentration measurement of particles in suspension is an important procedure performed in biological and clinical laboratories. Existing methods based on instruments such as hemocytometers, coulter counters, and flow cytometers are often laborious, destructive, and incapable of in vivo measurements. An ultrasound-based method has several unique advantages. It can be nondestructive and noninvasive, which allows a much larger portion of the sample to be analyzed, improving the accuracy and decreasing required sample volume. Also, ultrasound methods have the potential for in vivo measurement in the clinical setting, where cell concentration in liquids such as cerebrospinal fluid can be measured noninvasively without requiring a lumbar puncture. In this work, a new method is presented that estimates absolute particle concentration from high frequency B-mode ultrasound images. The method is based on the detection and characterization of the echoes from individual particles to estimate the effective slice thickness of the image. Prior characterization of the sample is not required because the estimation relies only on parameters that are measured directly from the image. The particle type differential is also performed by using the backscatter coefficient. The method is demonstrated by measuring microsphere suspensions as well as human T cell suspensions using a mechanically scanned single element transducer imaging system and a VisualSonics Vevo 2100. The proposed method has a wide range of potential clinical applications including noninvasive measurement of cell concentration in biological fluids.

Available in PDF, EPUB and Kindle. Book excerpt: Processing of Solid-Liquid Suspensions is a collection of articles from several industrialists and academicians who are active in fundamental and applied research relating to handling and processing of particles in liquids. This collection of papers deals with the processes of interaction of particles with each other, with the surrounding liquid and process equipment, whereby knowledge of the mechanism of these interactions can be a sound basis for improving the design of the process equipment and create an optimum environment for the formation and processing of the particulate. The above notion is explained through analysis of the role of turbulent aggregation and breakup of particles in the formation of many solid products from aqueous solutions. This book also analyzes particle size and particulate crystals, whether as final products or as intermediates during processing. In the purification of proteins, two essential units of operation are used; precipitation and solid-liquid separation are analyzed, where theoretical considerations are reviewed. This text also discusses the application of model suspensions in the design of aerobic fermenters in practical industrial uses. High concentration of suspension preparations and solid suspension in liquid flourized beds or in stirred vessels are explained in more detail as to how these affect certain industries. This selection finally presents the progress made in developing design and methods needed by industry. Researchers, chemists, and scientists in industry, as well as advanced students with interests in formation and processing of stable suspensions and in advanced process engineering courses will find this textbook a valuable aid.

Download or read book Non Invasive Characterization Of A Flowing Multi Phase Fluid Using Ultrasonic Interferometry written by and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An apparatus for noninvasively monitoring the flow and/or the composition of a flowing liquid using ultrasound is described. The position of the resonance peaks for a fluid excited by a swept-frequency ultrasonic signal have been found to change frequency both in response to a change in composition and in response to a change in the flow velocity thereof. Additionally, the distance between successive resonance peaks does not change as a function of flow, but rather in response to a change in composition. Thus, a measurement of both parameters (resonance position and resonance spacing), once calibrated, permits the simultaneous determination of flow rate and composition using the apparatus and method of the present invention.

This book was released on 1997 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: A swept-frequency ultrasonic interferometry technique is used for noninvasively determining acoustic properties of fluids inside containers. Measurements over a frequency range 1-15 MHz on six liquid chemicals are presented. Measurements were made with the liquid inside standard rectangular optical glass cells and stainless steel cylindrical shells. A theoretical model based on one-dimensional planar acoustic wave propagation through multi-layered media is employed for the interpretation of the observed resonance (interference) spectrum. Two analytical methods, derived from the transmission model are used for determination of sound speed, sound attenuation coefficient, and density of liquids from the relative amplitude and half-power peak width of the observed resonance peaks. Effects of the container material and geometrical properties, path-length, wall thickness are also studied. This study shows that the interferometry technique and the experimental method developed are capable of accurate determination of sound speed, sound attenuation, and density in fluids completely noninvasively. It is a capable and versatile fluid characterization technique and has many potential NDE applications.
