Book Synopsis Combustion Behavior of Solid Fuel Ramjets, Vol. 1. Correlation of Reacting and Non-reacting Flow Characteristics by : Brian A. Binn
Download or read book Combustion Behavior of Solid Fuel Ramjets, Vol. 1. Correlation of Reacting and Non-reacting Flow Characteristics written by Brian A. Binn and published by . This book was released on 1981 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was conducted to determine the relationship between the cold flow characteristics of velocity, pressure distribution, and turbulence intensity and the reacting flow performance and combustion characteristics of a solid fuel ramjet. The effects of configuration and air flow changes on the above characteristics were examined. Average regression rates and combustion efficiencies were not significantly affected by changes in configuration. These variations in test conditions significantly affected the centerline turbulence intensity but not the near-wall turbulence intensity in cold flow. Near-wall turbulence profiles in cold flow were found to correlate with the fuel regression profiles in reacting flows. The use of bypass resulted in decreases in regression rate and efficiencies for all cases. (Author).

This book was released on 1979 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An adaptation of a primitive variable, finite-difference computer program was accomplished in order to predict the reacting flow field in a solid fuel ramjet. The study compares the predictions of the primitive variable computer model with an earlier computer model and empirical data. It was found that the new model reasonably predicted the flow field and permitted calculations within the aft mixing chamber. (Author).

This book was released on 1979 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was conducted to determine if there is a relationship between the cold flow characteristics of velocity, pressure distribution, and turbulence intensity and the reacting flow performance and combustion characteristics of a solid fuel ramjet. The effects of configuration and air flow changes on the above characteristics were examined. Average regression rates and combustion efficiencies were not significantly affected by changes in configuration. These variations in test conditions significantly affected the center-line turbulence intensity but not the near-wall turbulence intensity in cold flow. The use of bypass resulted in decreases in regression rate and efficiencies for all cases. Attainable performance appears to be most strongly related to near-wall turbulence intensity/mixing and to the amount of fuel reaching the aft mixing chamber. (Author).

Download or read book An Investigation of the Reacting and Non-Reacting Flow Characteristics of Solid Fuel Ramjets written by Winston Elliott Scott and published by . This book was released on 1980 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted to determine the relationship between the non-reacting and the reacting flow characteristics of solid fuel ramjets. Polymethylmethacrylate fuel grains were burned in a ramjet motor on a thrust stand. Combustion efficiency, regression rate profile and pressures were determined for the reacting flows and compared to profiles obtained in non-reacting flows for velocity, pressure, and near-wall and centerline turbulence intensity. Near-wall turbulence profiles were in agreement with the fuel regression profiles obtained in reacting flows. Combustion efficiency was found to be a strong function of mixture ratio. Near-wall mixing significantly increased fuel regression rate. (Author).

Book Synopsis Masters Theses in the Pure and Applied Sciences by : Wade H. Shafer
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer. This book was released on 1986-07-01 with total page 424 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 Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, 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 29 (thesis year 1984) a total of 12,637 theses titles from 23 Canadian and 202 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 29 reports theses submitted in 1984, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: The calculated results based on the universal two-equation model known as k-epsilon model of turbulence for recirculating, reactive and non-reactive flows in dump combustors (12 in. ID) are presented extending the previous results obtained in this Department. The experimental data on the combustion efficiency, flow fields and recirculation zones for such combustors from the Air Force Aero Propulsion Laboratory, Ohio and the Arnold Engineering Development Centre, Tennessee have been compared with those predicted by the present modelling procedure and found to be in remarkably good agreement.

Book Synopsis Flow Characteristics in Solid Fuel Ramjets by : Joseph Theodore Phaneuf
Download or read book Flow Characteristics in Solid Fuel Ramjets written by Joseph Theodore Phaneuf and published by . This book was released on 1974 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation of the internal ballistics of solid fuel ramjets was conducted in order to determine the effects of inlet step size, inlet velocity and wall blowing on flow characteristics behind a backward facing step inlet. It was shown that the reattachment point (zone) moves toward the step inlet with wall mass addition at a constant inlet mass flux. For a given step inlet, however, the leading edge of the reattachment zone was stationary with variations in inlet velocity. A point where the wall temperature and centerline static pressure profiles leveled off simultaneously was defined as the end of the reattachment zone. This zone spread out (grew thicker) both with increasing inlet velocity for a given step size, and with increasing step height. Maximum wall temperatures occurred downstream of the reattachment zone.
