Available in PDF, EPUB and Kindle. Book excerpt: One of the most challenging problems of modern engineering is undoubtedly the prediction of hypersonic flows around space vehicles in reentry conditions. Indeed, the difficulties are numerous: first of all, these flows are very difficult to model, since very complex physical and chemical phenomena take place during the reentry phase; secondly, temperature, velocity and enthalpy are very high and densities are very low, making the reentry process very difficult to reproduce in ground-based experiments. The past three decades have seen important efforts in computational fluid dynam ics relying on the use of supercomputers to simulate these very complicated flows. The numerical simulation based on imperfect models and methods which were es sentially designed for transonic and supersonic flows has still a long way to go in order to be able to predict these hypersonic reentry flows very accurately. This situation has motivated very strong international cooperative efforts with, as the most visible consequences, the EuropelUnited States Short Courses on Hy personics, which were held in Paris, in 1987 [1,2], Colorado Springs in 1989 [3], and Aachen in 1990 [3]. The workshop on Hypersonics whose results are presented and analysed in these volumes is also a direct consequence of this international cooperation. This scien tific event was an initiative of P. Perrier, Head of the Theoretical Aerodynamics Department of DASSAULT AVIATION, who played a key role in the identification of the critical problems and the realisation of experiments, within the Hermes R&D program framework.

This book was released on 2012-12-06 with total page 1231 pages. Available in PDF, EPUB and Kindle. Book excerpt: This entry describes the experimental work conducted in the Department of Aeronautics at Imperial College in connection with Test Problems 1 and 2 of the "Workshop on Hypersonic Flows for Reentry Problems, Part I". These are defined as follows: Test Problem 1 Flow Over a Slender Cone Test Problem 2 Turbulent Base Flow The main requirement of this text is to present the experimental data for direct comparison with the predictions of CFD codes. We have therefore concentrated mainly on a factual statement of measuring techniques and results, together with an assessment of experimental accuracy. Future publications will be devoted to more extensive physical interpretations and discussions of the results. We have produced a large volume of data, some of which were categorised as "MANDATORY" and some as "OPTIONAL" for the purposes of CFD validation. However, only the "MANDATORY" data are presented here, although the other data are available and will be published separately later. 2. EXPERIMENTAL ARRANGEMENT 2. 1 The Test Facility The experiments were conducted in the Imperial College No. 2 Gun tunnel. This facility is a conventional intermittent blowdown tunnel with a contoured Mach 9 (nominal) axisymmetric nozzle fed by a free piston compression heater.

Available in PDF, EPUB and Kindle. Book excerpt: One of the great challenges of modem aerospace engineering is undoubt edly the prediction of hypersonic flows for the design of space vehicles. An important and continuous effort has taken place in that direction the last few years with the development of hypersonics programs such as the NASP program in the U. S. and more recently the HERMES program in Europe, which rely heavily on the the use of supercomputers. As can be expected this great challenge has been influencing both civil and military programs related to aerospace sciences and industry. Advanced mathematical models are a basic requirement for the de velopment of efficient numerical methods able to simulate accurately the phenomena that occur during the hypersonic part of the flight of space vehicles. Despite continuous advances in computer hardware and software and also the experience gained during the past three decades by researchers who have provided guidance for those who follow now, we strongly be lieve that a better understanding of hypersonic flow is still an important factor of scientific and technological progress. On the basis of this belief, the International Workshop on Hypersonic Flows for Reentry Problems, Part II, took place in Antibes, France, from 15 to 19 April 1991. This workshop, whose proceedings form this volume, was a clear continua tion of the Euro-American short courses on hypersonics held in Paris in 1987, Colorado Springs in 1989, and Aachen in 1990 and the workshop on hypersonic flow which took place in Antibes, in January 1990.
