This book was released on 1965 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: A limited experimental investigation has been conducted to confirm the existence of exhaust backflow from a cluster of three widely spaced nozzles operating in a near-space environment and to determine pressure and heat- transfer coefficients in the region washed by the backflow. Experiments were conducted in a 61-foot-diameter vacuum sphere using a sine solid-propellant rocket motor and a reflection plate. The reflection plate was used to simulate the interference planes that would normally exist for a cluster of three nozzles. Data were obtained for nozzle spacings of 8.02 and 17.05 nozzle exit diameters for pressures which simulated a nominal altitude range of 3.2 x 109(exp 5) to 1.8 x 10(exp 5) feet. The pressure data indicated that the backflow was super- sonic for several nozzle exit diameters ahead (upstream) of the nozzle exit plane and that the flow over small-diameter thermocouples in this region was in the free-molecule region. Average heat-transfer coefficients obtained for small-diameter cylinders (thermocouples) in this region were on the order of 1 x 10(exp -4) Btu/sq ft-sec-degrees R.

Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted to determine the effect of temperature and composition on alloy softening in group VIA metals Cr, Mo, and W alloyed with Re. Results showed that alloy softening was similar in all three alloy systems occurring at homologous temperatures less than 0.16 and at Re concentrations less than 16 atom percent. Rhenium content required to produce a hardness minimum diminished rapidly in all three systems with increasing test temperature. The similarities in hardness behavior in these three alloy systems suggesat common softening mechanism which may arise from lowering the Peierls stress.

This book was released on 1973 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: A potential interference problem for the Viking '75 scientific investigation of the Martian surface resulting from retrorocket exhaust plume impingement of the surface was investigated experimentally and analytically. It was discovered that the conventional bell nozzle originally planned for the Viking Lander retrorockets would produce an unacceptably large amount of physical disturbance to the landing site. An experimental program was subsequently undertaken to find and/or develop a nozzle configuration which would significantly reduce the site alteration. A multiple nozzle configuration, consisting of 18 small bell nozzles, was shown to produce a level of disturbance that was considered by the Viking Lander Science Teams to be acceptable on the basis of results from full-scale tests on simulated Martian soils.

This book was released on 2024-09-11 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: A simulation is the imitation of the operation of a real-world process or system over time. Simulations require the use of models in which a model represents the key characteristics or behaviors of the selected system or process and the simulation represents the evolution of the model over time. Computers are often used to execute simulations. This book provides a comprehensive overview of simulation modeling and explores its use to solve a large set of problems. It is a useful resource for scholars, researchers, and undergraduate and graduate students in pure and applied mathematics, physical sciences, engineering and technology, computer science, numerical analysis, scientific computing, and science in general.
