Available in PDF, EPUB and Kindle. Book excerpt: Detailed flowfield results have been obtained for sphere-cone shaped bodies at various angles of attack with a 3D nonequilibrium viscous-shock-layer (VSL) code. Recently obtained surface and shock-slip boundary conditions are implemented to account for the low-density effects. These boundary conditions may also be employed with the Navier-Stokes equations with or without a shock-fitting solution technique. A method is suggested for obtaining the input shock shape for the 3D nonequilibrium viscous flow. This approach gives a superior convergence of results, especially under the low-density flow conditions and makes the VSL method self-starting. The analytic algebraic grid implemented with the equations does not add any numerical dissipation. Obtained results show the effect of low density on the surrounding flowfield and surface quantities for a hypervelocity vehicle. Good agreement is obtained with the available numerical results (including the Direct Simulation Monte-Carlo predictions) and experimental data for the low-density flight conditions. Keywords: Axisymmetric hypervelocity vehicles; Three-dimensional flow; Low density flow fields; Viscous shock layer equations; Nonequilibrium viscous flow; Angle of attack. (EDC).

This book was released on 2012-12-06 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, a rapid growth of knowledge in the field of re-entry and planetary entry has resulted in many significant advances useful to the student, engineer and scientist. The purpose of offering this course is to make available to them these recent significant advances in physics and technology. Accordingly, this course is organized into five parts: Part 1, Entry Dynamics, Thermodynamics, Physics and Radiation; Part 2, Entry Abla tion and Heat Transfer; Part 3, Entry Experimentation; Part 4, Entry Concepts and Technology; and Part 5, Advanced Entry Programs. It is written in such a way so that it may easily be adopted by other universities as a textbook for a two semesters senior or graduate course on the sub ject. In addition to the undersigned who served as the course instructor and wrote Chapters, 1, 2, 3 and 4, guest lecturers included: Prof. FRANKLIN K. MOORE who wrote Chapter 5 "Entry Radiative Transfer," Prof. SHIH-I PAl who wrote Chapter 6 "Entry Radiation-Magnetogasdy namics," Dr. CARL GAZLEY, Jr. who wrote Chapter 7 "Entry Deaccelera tion and Mass Change of an Ablating Body," Dr. SINCLAIRE M.
