Download or read book Flow Visualization of Time-Varying Structural Characteristics of Dean Vortices in a Curved Channel written by David Wayne Bella and published by . This book was released on 1988 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: The time varying development and structure of Dean vortices were studied using flow visualization. Observations were made over a range of Dean numbers from 40 to 200 using a transparent channel with mild curvature, 40:1 aspect ratio, and an inner to outer radius ratio of 0.979. Seven flow visualization techniques were tried but only one, a wood burning smoke generator, produced usable results. Different vortex characteristics were observed and documented in sequences of photographs spaced one quarter of a second apart at locations ranging from 85 to 135 degrees from the start of curvature. Evidence is presented that supports the twisting/rocking nature of the flow. keywords: Curved heat transfer; Centrifugal instabilities. (KR).
Book Synopsis The Development and Structural Characteristics of Dean Vortices in a Curved Rectangular Channel by : Lawrence Richard Baun
Download or read book The Development and Structural Characteristics of Dean Vortices in a Curved Rectangular Channel written by Lawrence Richard Baun and published by . This book was released on 1988 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development and structure of Dean vortices in a curved channel were measured and studied. A 40:1 aspect ratio channel with mild curvature was employed. Circulation of mean streamwise vorticity, and maxima of streamwise, spanwise and radial components of vorticity increase as the Dean number increases from 40 to 140. Mean vorticity components were determined from measurements of the three components of mean velocity using a miniature five hole pressure probe. Spectra obtained from a subminiature crossed wire probe show principal and harmonic frequencies for Dean numbers greater than 165, when vortices are twisting. Spectral peaks at other Dean numbers provide evidence of oscillations also observed during flow visualization. Keywords: Dean vortices, Dean number, Channel flow, Rectangular curved channel, Theses.

This book was released on 2012-12-06 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * at Purdue. University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Synopsis A Flow Visualization Study of Laminar/Turbulent Transition in a Curved Channel by : Marc A. Siedband
Download or read book A Flow Visualization Study of Laminar/Turbulent Transition in a Curved Channel written by Marc A. Siedband and published by . This book was released on 1987 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laminar/turbulent transition was studied as it occurs in a newly constructed curved channel of rectangular cross section. The channel is 1.27 centimeters high by 50.8 centimeters wide (0.5 in. x 20 in.), aspect ratio of 40 to 1, with a concave surface radius of curvature of 60.96 centimeters (24 in.). Mean velocities for air in the channel range from 1.40 to 3.89 m/sec, which corresponds to Dean number and hydraulic Reynolds number ranges of 167 to 4651 and 2,231 to 6,173, respectively. Flow visualization from a smoke ire shows changes in the behavior and appearance of a smoke trace illuminated in the radial plane with varying Dean number and varying channel location. In some cases, these smoke trace patterns show distortion similar to what would be expected if pairs of counter-rotating vortices are present. A map of vortex stability as channel location and Dean number were varied was constructed from analysis of smoke trace photographs. Keywords: Dean vortices; Taylor Gortler vortices; Dean number; Rectangular curved channel; Secondary flow; Laminar flow; Concave curvature; Convex curvature; Thesis.
