Available in PDF, EPUB and Kindle. Book excerpt: A dual, axially-in-line, side-dump, liquid-fueled ramjet combustor was designed and tested with varying fuel-air ratios, atomizer types, and air distributions between the two inlets. Particle size distributions produced by the atomizers were measured at the inlet duct plane. When operated in a contra- flow direction, all of the atomizers produced excellent atomization with a Sauter mean diameter less than 14 microns. The dual, in-line inlets provided improved flammability limits and combustion efficiencies at lean fuel-air ratios when compared to single side-dump performance. Direct injection of approximately 20% of the fuel flow into the dome region was found to provide improved lean flammability limits for the single side-dump, but was not required with the dual inlets. The fuel distribution in the inlet duct required for good flammability limits and combustion efficiency was opposite to that required to prevent pressure oscillations, indicating that a dump plane aero-grid will often be necessary. A dump angle of 45 deg resulted in lower than desired combustion efficiencies, apparently due to poor mixing with the air from the aft inlet.

This book was released on 1993 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three distinct inlet-side-dump ramjet-combustor geometric configurations were investigated. Non-intrusive watertunnel flow-visualization techniques were utilized to qualitatively determine optimum flame-stabilization dome lengths and fuel-injection locations. The results were in good agreement with the results from previous studies. The optimum dome lengths which provided good fuel distribution and steady mixing all had lengths between 0.31 D and 1.4 D. Fuel injection in a narrow region on the upstream side of the inlet cross section was the only location capable of distributing fuel into the flame- holding region. Multiple injection locations in the inlet were required to distribute fuel uniformly into the main combustion region. The dual, axially-in- line side-dump configuration demonstrated the best potential for increasing performance across a wide range of operating conditions due to the ancillary combustion region between the inlets and the ability to control the size and strength of the region by varying air mass flow through the two inlet dumps.

Available in PDF, EPUB and Kindle. Book excerpt: Thermoacoustic Combustion Instability Control: Engineering Applications and Computer Codes provides a unique opportunity for researchers, students and engineers to access recent developments from technical, theoretical and engineering perspectives. The book is a compendium of the most recent advances in theoretical and computational modeling and the thermoacoustic instability phenomena associated with multi-dimensional computing methods and recent developments in signal-processing techniques. These include, but are not restricted to a real-time observer, proper orthogonal decomposition (POD), dynamic mode decomposition, Galerkin expansion, empirical mode decomposition, the Lattice Boltzmann method, and associated numerical and analytical approaches. The fundamental physics of thermoacoustic instability occurs in both macro- and micro-scale combustors. Practical methods for alleviating common problems are presented in the book with an analytical approach to arm readers with the tools they need to apply in their own industrial or research setting. Readers will benefit from practicing the worked examples and the training provided on computer coding for combustion technology to achieve useful results and simulations that advance their knowledge and research. Focuses on applications of theoretical and numerical modes with computer codes relevant to combustion technology Includes the most recent modeling and analytical developments motivated by empirical experimental observations in a highly visual way Provides self-contained chapters that include a comprehensive, introductory section that ensures any readers new to this topic are equipped with required technical terms
