This book was released on 2017 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is done as a requirement for the master’s degree. In this work, a system for generating aerosol delivery into shock tube for interface creation and a method to measure aerosol is developed. In chapter 1, a brief introduction of hydrodynamic instabilities later focussing on shock driven multiphase instabilities (SDMI) and its importance is presented. SDMIs have similar flow morphology to the Richtmeyer-Meshkov Instability (RMI), however, the driving force that induces instability is different. Current methods of aerosol production and measurement with pros and cons are given to justify the adaption of the selected method for our system. Chapter 2 discusses about the theory of ultrasonic atomization and evidence of faraday instability for atomization. Later setup of aerosol delivery system with two different set of atomizers is presented. In chapter 3, Laser interferometry principle and apparatus used for the measurement of aerosol with the consideration of various factors is given. To avoid Mie scattering theory's intense use of calculations Geometrical optics approximation method is used which agrees well with the Mie theory for all the particles above 1[mu]m. Chapter 4 presents experimental results of measurement which includes particle size distribution, density measurement of aerosol. Later it presents the experimental results when the aerosol is used for the study of SDMI. Two different cases, one with the low effective Atwood number and the other with higher effective Atwood number are investigated. In the case of low effective Atwood number the instability evolved is more like RMI rather than SDMI which is due to domination of Gas Atwood number over effect Atwood number. Last case with higher effective Atwood number of 0.03 with shock wave of Mach 1.66 is investigated, to find out that flow morphologies are in good agreement with literature and simulations. Chapter 5 gives conclusion of the research studies and future research.

Book excerpt: Fine Particles: Aerosol Generation, Measurement, Sampling, and Analysis is a collection of technical papers presented at the Symposium on Fine Particles held in Minneapolis, Minnesota, on May 28-30, 1975. The symposium aims to explore the developments in instrumentation and experimental techniques for aerosol studies. This book is organized into four parts encompassing 34 chapters that focus on fine particles below about 3.5 μm in diameter. Part I presents the research and development in Europe and Japan on fine particles and aerosols, as well as the aerosol standards development work at the Particle Technology Laboratory, University of Minnesota. This part also includes calibration studies on condensation nuclei counters and the diffusion battery. Significant chapters in Part II are devoted to the common techniques for generation of aerosols of various sizes, from fine particles to monodisperse aerosols. This part further looks into the equipment limitations and problems in producing fine particle aerosols for life testing air cleaning systems and for weather modification experimentation. Part III describes the techniques and equipment used for size-selective aerosol sampling in terms of the design principles applied, the correspondence between design and performance of specific samplers, their applicability to field conditions, and their ability to satisfy sampler acceptance criteria. Part IV deals first with the methods for determination of aerosol properties, including their optical, electrical, and spectral properties. Other chapters examine the principles, mode of operation, and application of processes and instruments for aerosol studies.

Download or read book Design Construction and Experimental Characterization of a Versatile Apparatus for Detecting Individual Aerosol Particles written by Xihong Wu and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental characterization has been carried out to determine the particle beam width and transmission efficiency for an inlet specially designed to focus particles in the range of 0.5-10 microns. A dual-color fluorescence correlation method has been employed to investigate coincidence effects and consequently to optimize the aerosol concentration so as to guarantee the single particle detection. The performance of the system has been demonstrated by measuring spectrally-resolved and time-resolved fluorescence of single dye-doped fluorescent particles and biological simulants such as tryptophan and NADH aerosols.

Download or read book Apparatus for Rapid Measurement of Aerosol Bulk Chemical Composition written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An apparatus and method for continuous on-line measurement of chemical composition of aerosol particles with a fast time resolution are provided. The apparatus includes a modified particle size magnifier for producing activated aerosol particles and a collection device which collects the activated aerosol particles into a liquid stream for quantitative analysis by analytical methods. The method provided for on-line measurement of chemical composition of aerosol particles includes exposing aerosol carrying sample air to hot saturated steam thereby forming activated aerosol particles; collecting the activated aerosol particles by a collection device for delivery as a jet stream onto an impaction surface; flushing off the activated aerosol particles from the impaction surface into a liquid stream for delivery of the collected liquid stream to an analytical instrument for quantitative measurement.
