      Eswar Josyula serves as a research engineer in the hypersonic sciences branch at the Air Force Research Laboratory. An associate fellow of the AIAA, his research interests include computational fluid dynamics of hypersonic nonequilibrium flow systems, state-to-state kinetics, transport coefficients, and hybrid kinetic and continuum methods. The High Temperature Aspects of Hypersonic Flow is a record of the proceedings of the AGARD-NATO Specialists' Meeting, held at the Technical Centre for Experimental Aerodynamics, Rhode-Saint-Genese, Belgium in April The book contains the papers presented during the meeting that tackled a broad range of topics in the aspects of hypersonic.

    The current resurgence of interest in hypersonic technologies has warranted an inquiry into the commonly employed thermochemical non-equilibrium models within computational fluid dynamic (CFD) simulations. Additionally, research has historically focused on forebody flowfields, while studies of the complex wake structure have remained elusive. Although the forebody is of significance for.   The Computational AeroSciences Branch performs computational research in aerodynamics and acoustics with applications in all speed regimes, from subsonic to hypersonic flight. The Branch works to improve fundamental understanding of physics associated with the fluid mechanics and noise generation for complex airframe systems.

    Tamer Zaki, the winner of the Office of Naval Research Young Investigator Award, is recognized for his innovative theoretical and engineering solutions to technological and environmental challenges created when turbulence meets momentum, heat, and is an associate professor in the Department of Mechanical Engineering. Zaki’s work offers novel applications for hydro and aero.

Recently, turbulence production in hypersonic wall-bounded flows (HWBFs) has become a cutting-edge scientific issue in the fluid mechanics community because of its new physics. A hypersonic flight that travels in the atmosphere at speeds above Ma 5 could substantially reduce the travel time down to 1 or 2 h between any two locations on the.

Survey arrays of ion probes have been used to study the structure of the ionized turbulent wakes of in. diameter spheres flown at 14 ft/s in atmospheres of nitrogen at pressures of and 20 Torr.

Although the entire shock layer around a hypersonic vehicle is marked by high temperatures and pressures, a large portion of the viscous drag and heating the vehicle experiences can be traced back to a thin region near the surface known as the boundary layer.

(See the article by John D. Anderson Jr, Physics Today, Decemberpage Hypersonic Nonequilibrium Flows documents recent, unprecedented scientific advances in the field of nonequilibrium processes for aerospace applications.

These advances have been driven primarily by interest in space access and exploration, or in developing military technologies involving hypersonic.

His book, Hypersonic Flow Theory, co-authored with Wallace D. Hayes, and reprinted by Dover in as Hypersonic Inviscid Flow, is still the basic book on this subject. Synthetic Fuels, written with R.
