Описание:In suspension plasma spraying technique, there is a vital demand to produce a uniform and non-pulsating spray. In this study, the two-phase flow inside the effervescent atomizers is numerically modeled. The main concern of atomization is to have a controllable and uniform spray. These numerical results are compared with the experimental data available in literature. Thus, understanding the behavior of gas and liquid flow through the nozzle is crucial to predict the condition of outcoming spray. Effervescent atomizers, in which a gas is bubbled into the bulk liquid through an aerator, have shown to be a technological alternative to the conventional atomizers when atomization of liquids with large variety of viscosity and density is required. The behavior of liquid film in the discharge passage is investigated using different Gas to Liquid mass flow Ratios (GLR). The effect of nano-sized solid particles concentration on the liquid film thickness at the exit of the atomizer is studied through the change in liquid bulk density and viscosity.

Of Time and Space and Other Things

Hydrogen, therefore, will be a Gas not made up of separate atoms as is the case with the inert gases, but of two-atom molecules. Something similar will be true in the case of fluorine (electronic distribution 2,7), oxygen (2,6) and nitrogen (2,5). The fluorine atom can contribute an electron and form a shared pool of two electrons with a,neighboring fluorine atom which also contributes an electron. Two oxygen atoms can contribute two electrons apiece to form a shared pool of four electrons, and two nitrogen atoms can contribute three electrons each and form a shared pool of six electrons. I In each case, the atoms will achieve the 2,8 distribution of neon at the cost of forining paired molecules. As a result, enough stability is achieved so that fluorine (F2). oxygen (02), and nitrogen (N2) are all Gases. The oxygen atom can also form a shared pool of two electrons with each of two neighbors, and those two neigh bors can form another shared pool of two electrons among themselves. The result is a combination of three oxygen atoms (O:j), each with a neon configuration ...»

Numerical Simulation of Gas Pipeline Networks: Theory, Computational Implementation, and Industrial Applications
These methods can be applied both at the stage of a pipeline network' s design and at the stage of its operation. They allow for the development of efficient automated hardware and software systems for the early detection and prevention of dangerous malfunctioning of a pipeline network. They can be of use for development and efficiency analysis concerning anti-terrorist activities at big industrial energy plants. Practical applications of computation technologies and methods of numerical simulation are illustrated with examples of solving industrial problems for gas industry enterprises. The authors demonstrate the efficiency of these technologies and the methods for improving the safety of the oil pipeline networks serving thermal power stations. The book is intended for scientists and engineers who deal with the design of pipeline networks, the analysis of their actual state, pipeline network insurance and control, improving their industrial safety and environmental friendliness, in the context of a wide range of environment-oriented measures. The material is also comprehensible to graduate students in technical high schools. The application of these methods and technologies is aimed at an integrated assessment of the state of the gas pipeline networks of industrial enterprises and the creation of efficient safe modes for their operation. The book considers computation technologies and methods for numerical simulation intended for solving the problems of improving the operational safety and the efficiency of industrial gas pipeline networks. This approach is based on modern methods of computational mechanics and mathematical optimization.

Two-Phase Locking
Note that the two-phase locking protocol (2PL protocol) shouldn' t be confused with the two-phase commit protocol (2PC protocol) for distributed transactions. It is also the name of the resulting class (set) of transaction schedules. In databases and transaction processing (transaction management), Two-phase locking, (2PL) is a concurrency control locking protocol, or mechanism, which guarantees serializability (e. g. , see Bernstein et al. 1987, Weikum and Vossen 2001). Using locks that block processes, 2PL may be subject to deadlocks that result from the mutual blocking of two transactions or more. 2PL is a super-class of Strong strict two-phase locking (SS2PL), also called Rigorousness, which is widely utilized for concurrency control in general-purpose database systems.

Perceptions through the use of Social Cognitive Theory Nursing Students' Perceptions of Two-Way Interactive Video. An Explanation of Nursing Students'
In doing so, this book will explore ways to potentially increase the quality and effectiveness of the nursing students' learning environment. Distance learning courses allow institutions to increase enrollment, thereby potentially increasing the number of future nurses. The serious shortage of qualified nurses and nursing faculty has led many nursing programs to adopt and increase the use of distance educational technology. As the use of technology increases, nursing programs must continually evaluate the educational experiences of both students and faculty and seek ways to improve delivery of instruction. Bandura' s (1986) Social Cognitive Theory may help in these endeavors.
