Book Synopsis The Evolution of a Gas Bubble in a Closed Volume of Stirred Liquid by : Peter Tikuisis
Download or read book The Evolution of a Gas Bubble in a Closed Volume of Stirred Liquid written by Peter Tikuisis and published by . This book was released on 1983 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rate of bubble evolution and hence the rate of mass transport across a curved liquid-gas interface has been examined both theoretically and experimentally. The closed liquid volume constraint provides the mechanism by which the gas bubble may be placed initially in a state of stable equilibrium, thus allowing an accurate determination of the system parameters. The stirred liquid condition is measured with the use of laser-doppler anemometry. Through an experimental examination on the complete dissolution of nitrogen gas bubbles in water, the mechanism of mass transport is shown to be consistent with a model comprised of two processes: (1) the primary and rate-limiting process is modelled by the diffusion of gas through an unstirred liquid boundary layer whose thickness varies with bubble radius, and (2) a second-order limitation is shown to be due to the condition of non-equilibrium of the gas component at the phase boundary. The non-linearity of mass transport is shown to increase as curvature of the liquid-gas interface increases. (Author).

Book Synopsis The Physical Processes of Digestion by : Roger G. Lentle
Download or read book The Physical Processes of Digestion written by Roger G. Lentle and published by Springer Science & Business Media. This book was released on 2011-06-03 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food research (and funding) is becoming more and more focused on health. While researchers and product developers have made great strides in food engineering, there needs to be increased focus on what happens when the food is actually digested. How is the food absorbed? Do the benefits remain? Digestion is a complex topic, and this will be the first book aimed at food researchers. Authored by a physiologist and a food engineer, the book will be a welcome addition to the literature.
Book Synopsis Mechanics of Bubbles in Sludges and Slurries. 1998 Annual Progress Report by :
Download or read book Mechanics of Bubbles in Sludges and Slurries. 1998 Annual Progress Report written by and published by . This book was released on 1998 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous studies have established that the waste level of Hanford tanks responds to barometric pressure changes, the compressibility of retained bubbles accounts for the level changes, and the volume of retained gas can be determined from the measured waste level and barometric pressure changes. However, interactions between the gas bubbles and rheologically complex waste cause inaccurate retained gas estimates and are not well understood. Because the retained gas is typically a flammable mixture of hydrogen, ammonia, and nitrous oxide, accurate determination of the retained gas volume is a critical component for establishing the safety hazard of the tanks. Accurate estimates of retained gas from level/pressure data are highly desirable because direct in-situ measurements are very expensive in an individual tank and impossible in many single-shell tanks. The objective of this research project is to gain a fundamental understanding of the interactions between gas bubbles and tank waste during barometric pressure fluctuations. It is expected that the elucidation of the bubble/waste interaction mechanisms will lead to the development of models for a more accurate determination of: gas content in Hanford tanks, waste properties from level/pressure data, and the effect that barometric pressure fluctuations have on the slow release of bubbles. The results of this research will support critical operations at the Hanford Site associated with the flammable gas safety hazard and future waste operations such as salt-well pumping, waste transfers, and sluicing/retrieval. This three-year research program, which began in FY 1998, is divided into four related problems. Progress has been made in each of the areas of modeling bubble behavior in continuum materials (sludges) from both a solid mechanics viewpoint and separately from a fluid mechanics viewpoint, modeling studies of compressible bubbles in particulate materials (slurries), and experimental studies of bubbles in both sludges and slurries.

Book excerpt: This project is focusing on key issues associated with the flammable gas safety hazard and its role in safe storage and in future waste operations such as salt-well pumping, waste transfers, and sluicing and retrieval of tank waste. The purpose of this project is to develop a basic understanding of how single bubbles (of flammable gases) behave in representative waste simulants and then develop a framework for predicting macroscopic full-tank behavior from the underlying single-bubble behavior. The specific objectives of this research are as follows: 1. quantitatively describe the interaction of bubbles with waste materials (both sludges and slurries) to understand the physical mechanisms by which barometric pressure changes give rise to a hysteresis between level and pressure 2. develop improved methods for estimating retained gas by properly accounting for the interactions of bubbles with the waste 3. determine how to estimate waste physical properties from the observed hysteresis and the limitations of these estimates 4. determine how barometric pressure fluctuations induce slow upward migration and release of gas bubbles.
Book Synopsis Study of Physical Properties, Gas Generation and Gas Retention in Simulated Hanford Waste by :
Download or read book Study of Physical Properties, Gas Generation and Gas Retention in Simulated Hanford Waste written by and published by . This book was released on 1993 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to establish the chemical and physical processes responsible for the generation and retention of gases within high-level waste from Tank 101-SY on the Hanford Site. This research, conducted using simulated waste on a laboratory scale, supports the development of mitigation/remediation strategies for Tank 101-SY. Simulated waste formulations are based on actual waste compositions. Selected physical properties of the simulated waste are compared to properties of actual Tank 101-SY waste samples. Laboratory studies using aged simulated waste show that significant gas generation occurs thermally at current tank temperatures ((approximately)60°C). Gas compositions include the same gases produced in actual tank waste, primarily N2, N2O, and H2. Gas stoichiometries have been shown to be greatly influenced by several organic and inorganic constituents within the simulated waste. Retention of gases in the simulated waste is in the form of bubble attachment to solid particles. This attachment phenomenon is related to the presence of organic constituents (HEDTA, EDTA, and citrate) of the simulated waste. A mechanism is discussed that relates the gas bubble/particle interactions to the partially hydrophobic surface produced on the solids by the organic constituents.
