Application of Molecular Tagging Diagnostics to Turbulent Mixing Enhancement and Control Studies


Book Description

Molecular Tagging Velocimetry (MTV) was used to study vorticity dynamics in several flows under investigation for mixing enhancement and control. The evolution of streamwise vorticity, responsible for a large increase in mixing in a confined wake flow, was measured. It was found that the streamwise vorticity has a peak value in excess of 70% of the peak spanwise vorticity. The MTV technique was extended to allow simultaneous whole field measurements of the velocity and a passive scalar on the basis of molecular tagging diagnostics. This new approach also offers a new capability for simultaneous flow visualization and vorticity mapping. The application of MTV to the study of unsteady separation resulted in boundary layer resolved measurements of flow separation in the vortex ring/wall interaction and dynamic stall over a pitching airfoil. The measurements of flow separation over a pitching airfoil, believed to be the first boundary layer resolved measurement of this phenomenon, show that the process of boundary layer separation occurs over a shorter time scale, and is more eruptive, than that captured by the computations to date.







Frontiers and Advances in Molecular Spectroscopy


Book Description

Frontiers and Advances in Molecular Spectroscopy once again brings together the most eminent scientists from around the world to describe their work at the cutting-edge of molecular spectroscopy. Much of what we know about atoms, molecules and the nature of matter has been obtained using spectroscopy over the last one hundred years or so. Going far beyond the topics discussed in Jaan Laane’s earlier book on the subject, these chapters describe new methodologies and applications, instrumental developments and theory, which are taking spectroscopy into still new frontiers. The robust range of topics once again demonstrates the wide utility of spectroscopic techniques. New topics include ultrafast spectroscopy of the transition state, SERS/far-uv spectroscopy, femtosecond coherent anti-Stokes Raman spectroscopy, high-resolution laser induced fluorescence spectroscopy, Raman spectroscopy and biosensors, vibrational optical activity, ultrafast two-dimensional spectroscopy, biology with x-ray lasers, isomerization dynamics and hydrogen bonding, single molecule imaging, spectra of intermediates, matrix isolation spectroscopy and more. Covers spectroscopic investigations on the cutting edge of science Written and edited by leading experts in their respective fields Allows researchers to access a broad range of essential modern spectroscopy content from a single source rather than wading through hundreds of scattered journal articles

Oil Spill Environmental Forensics


Book Description

Oil Spill Environmental Forensics provides a complete view of the various forensic techniques used to identify the source of an oil spill into the environment. The forensic procedures described within represent various methods from scientists throughout the world. The authors explore which analytical and interpretative techniques are best suited for a particular oil spill project. This handy reference also explores the use of these techniques in actual environmental oil spills. Famous incidents discussed include the Exxon Valdez incident in 1989 and the Guanabara Bay, Brazil 2000. The authors chronicle both the successes and failures of the techniques used for each of these events. Dr. Zhendi Wang is a senior research scientist and Head of Oil Spill Research of Environment Canada, working in the oil and toxic chemical spill research field. He has authored over 270 academic publications and won a number of national and international scientific honors and awards. Dr. Wang is a member of American Chemical Society (ACS), the Canadian Society for Chemistry (CSC), and the International Society of Environmental Forensics (ISEF). International experts show readers the forensic techniques used in oil spill investigations Provides the theoretical basis and practical applications for investigative techniques Contains numerous case studies demonstrating proven technique
