Book Description
New results are presented for inviscid, supersonic and hypersonic blunt-body flow fields obtained with a numerical time-dependent method patterned after that of Moretti and Abbett. In addition, important comments are made with regard to the physical and numerical nature of the method. Specifically, numerical results are presented for two-dimensional and axisymmetric parabolic and cubic blunt bodies as well as blunted wedges and cones; these results are presented for zero degrees angle of attack and for a calorically perfect gas with gamma = 1.4. The numerical results are compared with other existing theoretical and experimental data. Also, the effects of initial conditions and boundary conditions are systematically examined with regard to the convergence of the time-dependent numerical solutions, and the point is made that the initial conditions can not be completely arbitrary. Finally, in order to learn more about the performance of the time-dependent method, a numerical experiment is conducted to examine the unsteady propagation and region of influence of a slight pressure disturbance introduced at a point on the surface of a blunt body.

Book Description
From the authors of the bestselling ChiRunning comes a revolutionary program that blends the health benefits of walking with the core principles of T’ai Chi to deliver maximum physical, mental, and spiritual fitness. The low-impact health benefits of walking have made it one of the most popular forms of daily exercise. Yet few people experience all the benefits that walking can offer. In ChiWalking, Danny and Katherine Dreyer, well-known walking and running coaches, teach the walking technique they created that transforms walking from a mundane means of locomotion into an intensely rewarding practice that enhances mental, emotional, and physical well-being. Similar to Pilates, yoga, and T’ai Chi, ChiWalking emphasizes body alignment and mindfulness while strengthening the core muscles of the body. The five mindful steps of the ChiWalking program will get anyone, regardless of age or athletic ability, into great shape from head to toe, inside and out. 1. Get aligned. Develop great posture and better balance. 2. Engage your core. Make back and knee pain disappear. 3. Create balance. Walk faster, farther, and with less effort. 4. Make a choice. Choose from a menu of twelve great walks such as the Cardio Walk, the Energizing Walk, or the Walking Meditation, to keep your exercise program fresh. 5. Move forward. Make walking any distance a mindful, enjoyable experience, whether you’re a beginner or a seasoned walker.

Book Description
Harness the principles of synchronicity and flow to live better, work smarter, and find purpose in your life When we align with circumstance, circumstance aligns with us. Using a cutting-edge scientific theory of synchronicity, Sky Nelson-Isaacs presents a model for living "in the flow"--a state of optimal functioning, creative thinking, and seemingly effortless productivity. Nelson-Isaacs explains how our choices create meaning, translating current and original ideas from theoretical physics and quantum mechanics into accessible, actionable steps that we can all take to live lives in better alignment with who we are and who we want to be. By turns encouraging and empowering, Living in Flow helps us develop an informed relationship to meaning-making and purposefulness in our lives. From this we can align ourselves more effectively within our personal, professional, and community relationships to live more in flow.

Book Description
This book is a comprehensive and intensive book for graduate students in fluid dynamics as well as scientists, engineers and applied mathematicians. Offering a systematic introduction to the physical theory of vortical flows at graduate level, it considers the theory of vortical flows as a branch of fluid dynamics focusing on shearing process in fluid motion, measured by vorticity. It studies vortical flows according to their natural evolution stages,from being generated to dissipated. As preparation, the first three chapters of the book provide background knowledge for entering vortical flows. The rest of the book deals with vortices and vortical flows, following their natural evolution stages. Of various vortices the primary form is layer-like vortices or shear layers, and secondary but stronger form is axial vortices mainly formed by the rolling up of shear layers. Problems are given at the end of each chapter and Appendix, some for helping understanding the basic theories, and some involving specific applications; but the emphasis of both is always on physical thinking.

Book Description
Much-needed, fresh approach that brings a greater insight into the physical understanding of aerodynamics Based on the author’s decades of industrial experience with Boeing, this book helps students and practicing engineers to gain a greater physical understanding of aerodynamics. Relying on clear physical arguments and examples, Mclean provides a much-needed, fresh approach to this sometimes contentious subject without shying away from addressing "real" aerodynamic situations as opposed to the oversimplified ones frequently used for mathematical convenience. Motivated by the belief that engineering practice is enhanced in the long run by a robust understanding of the basics as well as real cause-and-effect relationships that lie behind the theory, he provides intuitive physical interpretations and explanations, debunking commonly-held misconceptions and misinterpretations, and building upon the contrasts provided by wrong explanations to strengthen understanding of the right ones. Provides a refreshing view of aerodynamics that is based on the author’s decades of industrial experience yet is always tied to basic fundamentals. Provides intuitive physical interpretations and explanations, debunking commonly-held misconceptions and misinterpretations Offers new insights to some familiar topics, for example, what the Biot-Savart law really means and why it causes so much confusion, what “Reynolds number” and “incompressible flow” really mean, and a real physical explanation for how an airfoil produces lift. Addresses "real" aerodynamic situations as opposed to the oversimplified ones frequently used for mathematical convenience, and omits mathematical details whenever the physical understanding can be conveyed without them.
