These proceedings collect the papers presented at the 30th International Symposium on Shock Waves (ISSW30), which was held in Tel-Aviv Israel from July 19 to July 24, 2015. The Symposium was organized by Ortra Ltd. The ISSW30 focused on the state of knowledge of the following areas: Nozzle Flow, Supersonic and Hypersonic Flows with Shocks, Supersonic Jets, Chemical Kinetics, Chemical Reacting Flows, Detonation, Combustion, Ignition, Shock Wave Reflection and Interaction, Shock Wave Interaction with Obstacles, Shock Wave Interaction with Porous Media, Shock Wave Interaction with Granular Media, Shock Wave Interaction with Dusty Media, Plasma, Magnetohyrdrodynamics, Re-entry to Earth Atmosphere, Shock Waves in Rarefied Gases, Shock Waves in Condensed Matter (Solids and Liquids), Shock Waves in Dense Gases, Shock Wave Focusing, Richtmyer-Meshkov Instability, Shock Boundary Layer Interaction, Multiphase Flow, Blast Waves, Facilities, Flow Visualization, and Numerical Methods. The two volumes serve as a reference for the participants of the ISSW30 and anyone interested in these fields.

Optical Metrology for Fluids, Combustion and Solids is the first practical handbook that presents the assemblage of the techniques necessary to provide a basic understanding of optical measurement for fluids, combustion, and solids. The use of light as a measurement tool has grown over the past twenty years from a narrowly specialized activity to a mainstay of modern research today. Until recently, the knowledge that could be extracted from the light interaction of light with physical objects was limited to specialized activities. The invention of the laser, the computer and microelectronics has enabled a measurement revolution such that virtually every parameter of engineering interest can be measured using the minimally intrusive properties of light. The authors of this book's chapters are leaders in this revolution. They work on the front lines of research in government, industry, and universities, inventing yet more ways to harness the power of light for the generation of knowledge.

This volume is presented as a tribute to "two icons from the world of optics"--in the words of editors Harvey (Center for Research and Education in Optics and Lasers, U. of Central Florida) and Hooker (electrical and computer and engineering, U. of Colorado)--both of whom have been affiliated with the Optical Sciences Center at the U. of Arizona. Twenty-one papers from a tribute conference, some highly technical and others more personal, detail the honorees contributions to optics and optics education. These are followed by 45 journal article reprints authored by Bob Shannon and Roland Shack or their students in the technical areas of optical design and analysis, image evaluation, applications of the marginal ray height--chief ray height diagram, optical testing, optical fabrication, phased telescope arrays, aberration theory, propagation effects in the atmosphere, and diffraction/surface scatter phenomena. Finally, 14 short, informal "anecdotes and accolades" of the two scientists are presented from the conference and elsewhere. Annotation :2005 Book News, Inc., Portland, OR (booknews.com).

A program of fundamental, experimental research and analysis has been conducted to design additional components necessary to modify, assemble and develop a ground-based facility (LENS) to duplicate flowfield environment around a hypersonic endo-atmospheric interceptor to evaluate optical seeker performance. Aero-optic instrumentation, used to measure the aero-optical characteristics of the viscous and shock layer over transpiration-and-filmed cooled nosetips at hypersonic speeds were also investigated. In the design of the facility, particular care was taken in designing the systems for a contamination-free hypersonic flow and in isolating the loads associated with the operation of the shock tunnel from the model support system and the aero- optic instrumentation. Five instrumentation systems, including holography, imagery, boresight/jitter, radiometry and spectrometry were evaluated to provide consistent evaluation in ENDO-LEAP mission environments. State-of-the-art CFD codes with capabilities determining the inherent salient flowfield features such as turbulence and reacting chemistry were investigated and the GASP code was selected as the basic computational method. The stress levels and motion of shock tunnels were studied and analyzed using two approaches, a numeric marching code and a numeric solution to the wave equation. A flight test program based on existing sounding rocket technology was examined in order to design a high confidence flight test to validate the LENS ground test results.
