An experimental investigation involving a thick, adiabatic, naturally turbulent, two-dimensional boundary layer undergoing separation has been completed at the Naval Ordnance Laboratory (NOL). Forward facing steps (with attached end plates) were used to induce boundary-layer separation for the particular case where the step heights, h, were less than the boundary-layer thickness, delta. The tests were conducted at a free-stream Mach number of 4.9 with a range of unit Reynolds numbers varying from 0.8 x 10 to the 6th power per foot to 4.0 x 10 to the 6th power per foot. The pressure distributions measured in the separated region ahead of the steps were found to be functions of both Re sub delta and h/delta for the turbulent boundary-layer separation case where h

Shock wave-boundary-layer interaction (SBLI) is a fundamental phenomenon in gas dynamics that is observed in many practical situations, ranging from transonic aircraft wings to hypersonic vehicles and engines. SBLIs have the potential to pose serious problems in a flowfield; hence they often prove to be a critical - or even design limiting - issue for many aerospace applications. This is the first book devoted solely to a comprehensive, state-of-the-art explanation of this phenomenon. It includes a description of the basic fluid mechanics of SBLIs plus contributions from leading international experts who share their insight into their physics and the impact they have in practical flow situations. This book is for practitioners and graduate students in aerodynamics who wish to familiarize themselves with all aspects of SBLI flows. It is a valuable resource for specialists because it compiles experimental, computational and theoretical knowledge in one place.

In this groundbreaking book, trauma expert J. Eric Gentry builds upon the pioneering insights of such luminaries as neuroscientist Stephen Porges, Judith Herman and Bessel van der Kolk to introduce Forward-Facing Trauma Therapy (FFTT), the next evolutionary leap in the treatment of traumatic stress. Unlike many traditional psychotherapies, FFTT eschews the assumption that psychological problems are caused by our faulty perceptions and skewed thought processes. Instead, FFTT addresses trauma and its destructive symptomology at its sourceour overcharged autonomic nervous systems and hypervigilant threat response resulting from our adaptation to painful past experiences. Dr. Gentry provides a step-by-step guide for implementing a three-pronged methodology and explains how and why the techniques work so effectively. He also demonstrates how anyone experiencing stress can apply FFTT to achieve immediate change and an enduring sense of joy, self-worth, and personal integrity.

Like the previous editions also the third edition of this book combines the detailed physical modeling of mechatronic systems and their precise numerical simulation using the Finite Element (FE) method. Thereby, the basic chapter concerning the Finite Element (FE) method is enhanced, provides now also a description of higher order finite elements (both for nodal and edge finite elements) and a detailed discussion of non-conforming mesh techniques. The author enhances and improves many discussions on principles and methods. In particular, more emphasis is put on the description of single fields by adding the flow field. Corresponding to these field, the book is augmented with the new chapter about coupled flow-structural mechanical systems. Thereby, the discussion of computational aeroacoustics is extended towards perturbation approaches, which allows a decomposition of flow and acoustic quantities within the flow region. Last but not least, applications are updated and restructured so that the book meets modern demands.

A Mission To Help Others Heal. A mission to help others heal and regain productive lives is likely what led you to pursue a career in professional caregiving. But what happens when all the accumulated suffering and trauma that you have witnessed and the pain that you have experienced starts to cause problems in your own personal and professional life? Insidious and often steeped in shame, compassion fatigue burnout and traumatic stress are very real issues that members of the caregiving community are not only at risk for but will inevitably confront at some point in their careers. The key is not to fight against or run away from these consequences of caregiving, but to recognize their normalization, origination, and the applicable steps available to heal your existing stress and build resilience for the future. In Forward-Facing® Professional Resilience: Prevention and Resolution of Burnout, Toxic Stress and Compassion Fatigue, trauma and compassion fatigue expert Dr. J. Eric Gentry and medical director and practitioner of emergency medicine Dr. Jeffrey “Jim” Dietz combine over seventy years’ worth of experience treating patients and caregivers to present a two-part text that first examines the cause of compassion fatigue, followed by a proven, simple five-step solution for healing and a renewed sense of mission. Drawing from their Professional Resilience workshop that has been attended by over 100,000 international participants, Drs. Gentry and Dietz address these issues with their readers in ways that are candid, heartfelt, insightful, and most of all—filled with hope.

This book presents select proceedings of the International Conference on Innovations in Thermo-Fluid Engineering and Sciences (ICITFES 2020). It covers topics in theoretical and experimental fluid dynamics, numerical methods in heat transfer and fluid mechanics, different modes of heat transfer, multiphase flow, fluid machinery, fluid power, refrigeration and air conditioning, and cryogenics. The book will be helpful to the researchers, scientists, and professionals working in the field of fluid mechanics and machinery, and thermal engineering.

Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.

This book presents selected papers presented in the Symposium on Applied Aerodynamics and Design of Aerospace Vehicles (SAROD 2018), which was jointly organized by Aeronautical Development Agency (the nodal agency for the design and development of combat aircraft in India), Gas-Turbine Research Establishment (responsible for design and development of gas turbine engines for military applications), and CSIR-National Aerospace Laboratories (involved in major aerospace programs in the country such as SARAS program, LCA, Space Launch Vehicles, Missiles and UAVs). It brings together experiences of aerodynamicists in India as well as abroad in Aerospace Vehicle Design, Gas Turbine Engines, Missiles and related areas. It is a useful volume for researchers, professionals and students interested in diversified areas of aerospace engineering.
