NASA Glenn Research Center, the Department of Energy (DOE), and Stirling Technology Company (STC) of Kennewick, Washington are developing a Stirling convertor for a high-efficiency Stirling Radioisotope Power System to provide electric power for NASA Space Science Missions. STC is developing the 55-We Technology Demonstration Convertor (TDC) under contract to DOE. Steady-flow tests were completed to determine the friction factor for the high-porosity regenerators that are used in the TDC. STC fabricated a flow test fixture and three random fiber regenerator test samples, one each at approximately 80, 88, and 96 percent porosities. The flow tests were then completed by the NASA Glenn Flow Calibration Laboratory, and the data reduced to Reynolds number and friction factor. The results showed that the 80 and 88 percent porosity samples had similar characteristics while the 96 percent porosity sample had significantly higher friction factors for given Reynolds numbers compared to the samples with lower porosities. Comparisons were also made between the test data and existing correlations. STC used this data to derive a modified regenerator friction factor correlation for use in the Stirling design code GLIMPS for porosities greater than 88 percent. Using this new correlation, the final optimized regenerator design porosity was reduced from 96 to 90 percent. Thieme, Lanny G. Glenn Research Center NASA/TM-2001-211098, E-12943, NAS 1.15:211098

Stirling Convertor Regenerators addresses the latest developments and future possibilities in the science and practical application of Stirling engine regenerators and technology. Written by experts in the vanguard of alternative energy, this invaluable resource presents integral scientific details and design concepts associated with Stirling converter regenerators. Content is reinforced with novel insights and remarkable firsthand experience that the authors and their colleagues acquired while working at the National Aeronautics and Space Administration (NASA) and other leading organizations. Apply NASA Experience & Experimentation Intrigued by its special potential to improve energy generation, NASA has been working on Stirling technology since 1980—first for automotive applications, and later for use in generating auxiliary power during space missions. Now, after three decades of development, the Department of Energy and NASA and its contractors have developed a high-efficiency Stirling radioisotope generator (SRG), and NASA plans to launch such a Stirling engine/alternator for use in deep space. With contributions from top experts in their fields, this reference offers a rare insider’s perspective that can greatly benefit engineers, scientists, and even students who are currently working in R&D for Stirling machines, as well as other burgeoning areas of alternative power generation—particularly solar and wind technologies. This book is a significant resource for anyone working on application of porous materials in filters, catalytic convertors, thermal energy storage, electronic cooling, and more.

Through the integration of strategies from life science, engineering, and clinical medicine, tissue engineering and regenerative medicine hold the promise of new solutions to current health challenges. This rapidly developing field requires continual updates to the state-of-the-art knowledge in all of the aforementioned sciences. Tissue Engineering and Regenerative Medicine: A Nano Approach provides a compilation of the important aspects of tissue engineering and regenerative medicine, including dentistry, from fundamental principles to current advances and future trends. Written by internationally renowned scientists, engineers, and clinicians, the chapters cover the following areas: Nanobiomaterials and scaffolds—including nanocomposites and electrospun nanofibers Tissue mechanics Stem cells and nanobiomaterials Oral and cranial implants and regeneration of bone Cartilage tissue engineering Controlled release—DNA, RNA, and protein delivery Animal science and clinical medicine The editors designed this textbook with a distinctive theme focusing on the utilization of nanotechnology, biomaterials science in tissue engineering, and regenerative medicine with the inclusion of important clinical aspects. In addition to injured veterans and other individuals, increased life expectancy in the industrialized world is creating a growing population that will require regenerative medicine, producing greater pressure to develop procedures and treatments to improve quality of life. This book bridges the gap between nanotechnology and tissue engineering and regenerative medicine, facilitating the merger of these two fields and the important transition from laboratory discoveries to clinical applications.
