This book was released on 2000-06-01 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to obtain quantitative surface pressure measurements of a transonic compressor rotor using pressure sensitive paint (PSP), the temperature dependence of the paint must be taken into consideration. In the present study, a calibration chamber was built and instrumented such that pressure and temperature could be controlled independently. Photodiodes were used to measure the intensity of light emitted by the PSP. An acquisition program was developed to record the necessary calibration data to obtain an analytical representation of the luminescent response of the pressure-sensitive paint over a range of pressures and temperatures characteristic of transonic fans.

This book was released on 1998-09-01 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the development of a surface pressure measurement system for transonic compressor rotors, it has been shown that Pressure Sensitive Paint (PSP) is also temperature dependent. In the present study, the sensitivities to pressure and temperature were examined experimentally using an electronically- gated, intensified Charged- Coupled-Device (CCD) video camera, frame-grabber software and an eight-inch diameter calibration chamber. Using a signal generator, in a procedure that matched the requirements of the rotor application, multiple low-intensity-level camera exposures were integrated and captured to produce a single usable image. Ten captured images were averaged to increase the image's signal-to-noise ratio and the result was used to produce an image ratio with respect to a static (ambient pressure/temperature) reference condition. Calibration tests of constant temperature/variable pressure and constant pressure/variable temperature were completed. The results were then compared with data obtained using the same paint and an automated, single- exposure calibration procedure at NASA Ames Research Center. It was shown that the calibration data could be used to derive the static pressure field produced over a high-speed test rotor using PSP and the same image-capture system used in the calibration. In preparation for a bench test of the procedure, a uniform- stress, high-speed test rotor disk, fitted with a shock generator was driven at speeds in excess of 30,000 RPM. Recommendations are made toward the goal of obtaining quantitative pressure measurements on transonic compressor rotors.

Book Synopsis Calibrating Pressure Sensitive Paints Using Proper Orthogonal Decomposition by : Ahmed F. Omar
Download or read book Calibrating Pressure Sensitive Paints Using Proper Orthogonal Decomposition written by Ahmed F. Omar and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Pressure sensitive paints (PSP) have been gaining more popularity in experimental fluid mechanics and aerodynamic testing. A major problem with PSP pertains to its temperature dependence making the calibration process very difficult. Dual-luminophor PSP has an added temperature phosphor to provide temperature information for the calibration. Dual-luminophor system still suffer from the inherent temperature dependence and possess added complications due to spectral cross talk and overlap. However, to date there is no successful universal calibration technique for dual-luminophor systems. Such calibration is needed for dual-luminophor PSP to become a practical experimental tool. With this aim, a statistical technique known as proper orthogonal decomposition (POD) is used to extract pressure and temperature information from intensity data. POD works by defining and separating the main factors of any system and evaluating the proportional contribution of each factor. The calibration technique is examined by applying the dual-luminophor PSP in a channel flow experiment. Before applying the calibration experimentally, a set of artificial data is examined using POD to provide a fundamental understanding of POD as a calibration technique. The experiment was designed to allow for different flow conditions and temperature gradients to interact, hence providing enough variation to examine the calibration technique. Seven cases are examined, with each case shedding light on a particular aspect of the calibration. The POD calibration is compared to the intensity-ratio calibration in order to emphasize the effectiveness of the technique. Finally, results are evaluated for accuracy and a detailed uncertainty analysis is performed to fully assess the POD calibration.

Book excerpt: th This volume contains the papers presented at the 16 DGLR/STAB-Symposium held at the Eurogress Aachen and organized by RWTH Aachen University, Germany, November, 3 - 4, 2008. STAB is the German Aerospace Aerodynamics Association, founded towards the end of the 1970's, whereas DGLR is the German Society for Aeronautics and Astronautics (Deutsche Gesellschaft für Luft- und Raumfahrt - Lilienthal Oberth e.V.). The mission of STAB is to foster development and acceptance of the discipline “Aerodynamics” in Germany. One of its general guidelines is to concentrate resources and know-how in the involved institutions and to avoid duplication in research work as much as possible. Nowadays, this is more necessary than ever. The experience made in the past makes it easier now, to obtain new knowledge for solving today's and tomorrow's problems. STAB unites German scientists and engineers from universities, research-establishments and industry doing research and project work in numerical and experimental fluid mechanics and aerodynamics for aerospace and other applications. This has always been the basis of numerous common research activities sponsored by different funding agencies. Since 1986 the symposium has taken place at different locations in Germany every two years. In between STAB workshops regularly take place at the DLR in Göttingen.

Complementary volumes 9 and 10, Advanced Concepts of Fluorescence Sensing: Small Molecule Sensing and Advanced Concepts of Fluorescence Sensing: Macromolecular Sensing, aim to summarize the current state of the art in fluorescent sensing. For this reason, Drs. Geddes and Lakowicz have invited chapters, encompassing a broad range of fluorescence sensing techniques. Some chapters deal with small molecule sensors, such as for anions, cations, and CO2, while others summarize recent advances in protein-based and macromolecular sensors. The Editors have, however, not included DNA or RNA based sensing in this volume, as this were reviewed in Volume 7 and is to be the subject of a more detailed volume in the near future.
