Book Description
Written to teach students the nature of transonic flow and its mathematical foundation, this book offers a much-needed introduction to transonic aerodynamics. The authors present a quantitative and qualitative assessment of subsonic, supersonic and transonic flow around bodies in two and three dimensions. The book reviews the governing equations and explores their applications and limitations as employed in modeling and computational fluid dynamics. Some concepts, such as shock and expansion theory, are examined from a numerical perspective. Others, including shock-boundary-layer interaction, are discussed from a qualitative point of view. The book includes 60 examples and more than 200 practice problems. The authors also offer analytical methods such as Method of Characteristics (MOC) that allow readers to practice with the subject matter. The result is a wealth of insight into transonic flow phenomena and their impact on aircraft design, including compressibility effects, shock and expansion waves, shock-boundary-layer interaction and aeroelasticity.

Book Description
This new book leads readers step-by-step through the complexities encountered as moving objects approach and cross the sound barrier. The problems of transonic flight were apparent with the very first experimental flights of scale-model rockets when the disastrous impact of shock waves and flow separations caused the aircraft to spin wildly out of control. Today many of these problems have been overcome, and this book offers an introduction to the transonic theory that has made possible many of these advances. The emphasis is on the most important basic approaches to the solution of transonic problems. The book also includes explanations of common pitfalls that must be avoided. An effort has been made to derive the most important equations of inviscid and viscous transonic flow in sufficient detail so that even novices may feel confident in their problem-solving ability. The use of computer approaches is reviewed, with references to the extensive literature in this area, while the critical shortcomings of an exclusive reliance on computational methods are also described. The book will be valuable to anyone who needs to acquire an understanding of transonic flow, including practicing engineers as well as students of fluid mechanics.

Book Description
This book presents methods of studying transonic flows applicable to various astrophysical circumstances. This is the first book of its kind and efforts have been made to be as thorough as possible. It gives complete mathematical solutions for the study in this area including various shock transitions. For any theoretical astrophysicists this book is expected to be very useful as the formalism discussed can be applied to all the branches. Both axisymmetric and non-axisymmetric flows are studied.

Book Description
The main purpose of the report is to discuss some known available transonic flow approximate treatments and their applicabilities, including their limitations. This may suggest the possible future improvement of efforts in this renewed field. (Author).

Book Description
The contract concerned certain research topics in transonic flow, mainly addressing the questions of why corrections for entropy and viscosity to transonic potential theory were large in certain cases. The physical implications arising from the accurate use of each of these corrections are incompatible. The investigations is due to the fact that the potential equation admits non-unique solution branches and that the corrections, in addition to modeling entropy and viscosity, allow the potential solution to change to the correct branch. The study into the causes of the nonuniqueness was based on an integral equation formulation and the following results obtained. (a) The nonuniqueness only occur if there is a supersonic domain in the flow. (b) A nonunique solution does not have the same supersonic domain as the real solution. (c) The solution often can be made unique in steady flow by using a mixed conservative/nonconservative algorithm; this cannot be guaranteed however. (d) There is no way to differentiate between a solution that is physically correct and one that is not physically correct.

Book Description
This volume complements Transonic aerodynamics (v.81 in the series) which is concerned with steady flow. This is the only book to address the subject of unsteady transonic aerodynamics, a field much different from steady aerodynamics. The most pronounced difference is the complex shock wave motions
