Available in PDF, EPUB and Kindle. Book excerpt: A new technique for water tunnel flow visualization is based upon the use of a newly developed type of material--neutral-density, bi-liquid foams or 'polyaphrons'. These materials are small, spherical globules of one liqund encapsulated in a thin film of another liquid. It is now possible to make bi-liquid foams when the units are of micron or submircon size, and may be spherical or polyhedral depending upon the relative concentration of oil to water. They are easy to see and photograph in water and they can also be dyed to a variety of intense colors. In this two part study, polyaphrons were used for flow visualization in water tunnel tests of combustors. First, various formulations of the polyaphrons were made to optimize aphron size and density for water tunnel testing. Second, the best polyaphrons were used for flow visualization of real, prototype combustor model. Tests were conducted at 22.5 gpm. This corresponds to Re sub D=23,900, when D is the swirler diameter. Tests showed that polyaphron material proved easy to handle when injected through small tubes and the amount and ratio of injection was easy to control. No clogging of any kind was ever encountered. The pure material broke-up into clumps upon injection. A 50/50 mixture of water polyaphron eliminated clumping. Injection of polyaphrons was also directly compared with the more usual dye injection. Polyaphrons are ideal seeding material for Laser Doppler Velocimetry in water tunnels.

Book excerpt: The Defence Research Establishment Valcartier (DREV) in Canada and the TNO Prins Maurits Laboratory, Netherlands, have undertaken a collaborative activity (Integral Rocket Ramjet Demonstration Program - IRRDP) to demonstrate several of the key technologies of an air-breathing propulsion unit for a medium-range air-launched missile. An essential component of the propulsion system is the ducted rocket combustor, and as part of its development, experiments were conducted at TNO's direct-connect combustion test facility using existing sub-scale combustor hardware. To make the best use of the limited number of tests that could be carried out, a test matrix had to be carefully developed to determine which geometries and test conditions should be considered. This document presents much of the information used to develop this test matrix, to understand the phenomena investigated by other researchers, and identify which parameters were the most important for good air/fuel and combustor performance. Research work described includes visualization of flowfield within a model combustor in a water tunnel to better understand the air/fuel mixing, including flow stability; computational fluid dynamic modelling of the flow fields inside the combustor to determine whether the modelling was representative of the water tunnel tests; and modelling of additional combustor geometries.
Book Synopsis Flow Visualization by : Alexander J. Smits
Download or read book Flow Visualization written by Alexander J. Smits and published by World Scientific. This book was released on 2012 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the 2nd edition of the book, Flow Visualization: Techniques and Examples, which was published by Imperial College Press in 2000. Many of the chapters have been revised and updated to take into consideration recent changes in a number of flow visualization and measurement techniques, including an updated high quality flow gallery. Unique among similar publications, this book focuses on the practical rather than theoretical aspects. Obtaining high quality flow visualization results is, in many ways, more of an art than a science, and experience plays a key deciding role. The depth and breadth of the material will make this book invaluable to readers of all levels of experience in the field.

Book Synopsis Techniques of Flow Visualization by : Wolfgang Merzkirch
Download or read book Techniques of Flow Visualization written by Wolfgang Merzkirch and published by . This book was released on 1987 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The techniques of flow visualization and their application in wind tunnels, water channels, and experiments related to propulsion research are reviewed. These techniques can be classified roughly into three major groups: Surface flow visualization, scattering from flow tracers, and density sensitive flow visualization. The progress in laser optics and the wide-spread use of computers has led to the development of new techniques and evaluation procedures, which are included in the review; e.g. laser-induced fluorescence, speckle photography, image processing, and optical tomography. Emphasis is given to the discussion of the physical background of the methods. Information on technical details is provided by means of a number of sample photographs and by respective references.
