Masters Theses in the Pure and Applied Sciences
Author: Wade H. ShaferPublisher: Springer Science & Business Media
ISBN: 1461524539
Category : Science
Languages : en
Pages : 391
Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the though 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 concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemi nation. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation 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 37 (thesis year 1992) a total of 12,549 thesis titles from 25 Canadian and 153 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 37 reports theses submitted in 1992, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Design and Calibration of Seven Hole Probes for Flow Measurement

Languages : en
Pages : 324
Book Description
The calibration and use of seven hole pressure probes for hot flow measurement was studied extensively, and guidelines were developed for the calibration and use of these probes. The influence of tip shape, Reynolds number, calibration grid density, and curve fit were studied and reported. Calibration was done using the well established polynomial curve fit method of Gallington. An improvement to this method was proposed that improved the uniformity and magnitude of measurement error. A hemispherical tip was found to be less sensitive to manufacturing defects, and less sensitive to changes in tip Reynolds number than a conical tip. The response of the probes was found to be Reynolds number independent over a tip Reynolds number of 6000 for the entire calibrated range. For flows with an angle of attack less than approximately 20°, the response of the probe was found to be independent above Re = 3000. A minimum calibration grid density of 5° was recommended. Error in the measurement of high angle flows was found to increase significantly when the calibration grid was sparser than this. The response of the probe was found to contain features that were not properly represented by third order polynomial terms, and it was found that it was necessary to include fourth order terms in the polynomial curve fit. The uniformity of calibration error was found to improve significantly when the high angle sectors were calibrated using a small number of additional points from adjacent sectors. The calibration data sorting algorithm was modified to include a calibration point in a given sector if that sector's port read the highest pressure, or if that port read within a specified tolerance ("overlap pressure") of the highest pressure. An overlap pressure of 15-20% of the calibration flow dynamic pressure was found to decrease the maximum calibration errors by 10-15%.

A Method for Calibrating a Cone-probe Flow Field Measuring Instrument

Book Description
A simple method is presented for calibrating a cone-probe type of flow field measuring instrument. The calibration procedure requires data from only four orientations of the cone-probe in a quantitatively unknown flow field. Only changes in orientation must be known. It is then possible to use these data to determine the Mach number, total pressure, and flow angle of the unknown flow field; the constants in calibration equations for pitch and yaw flow angles; and the average static pressure. The method is verified by comparing with calibration results obtained in a conventional manner. (Author).
