Summary of Activities/Interests
We have extensive experience in conducting fundamental and applied research on environmental and industrial flows. We seek collaborative research opportunities on a variety of topics -- in particular, atmospheric and oceanic research with applications to ship and submarine wakes, ocean circulation, mine countermeasures, wind energy, contaminant dispersion and air pollution. We have published extensively on these topics, and reprints and reports are available upon request. Some of the interest areas are listed below; it is not an exhaustive list but was compiled to illustrate the diversity of topics, expertise and tools.
Wakes of Maneuvering Submarines and Submersibles:
With the support from the Office of Naval Research, we have developed a facility to conduct research on wakes of submerged maneuvering bodies, especially in the oceanic thermocline. We have a large water tank, with capabilities for obtaining density stratification, in which model submarines can perform different maneuvers. The interest is the dynamics of wakes and their penetration to the upper oceanic layers (Figure 1). We have IR remote sensing capabilities to study surface-penetrating wake signatures, and a suit of advanced flow diagnostic technologies is available for wake evolution studies.
IR Imaging of Ship Wakes and Surface Features
Recently we concluded a study for Raytheon Inc. on surface kinematics and dynamics of dual-propeller ship wakes based on IR Imaging (Figure 2). Very high resolution (>0.025K) IR Imaging capabilities were employed for this study. The same facility that is used for submarine research was used. In general, we have IR remote sensing capabilities for surface flow and wave studies as well as internal-surface wave interaction studies (http://efd.asu.edu/files/Raytheon.pdf).
Mine Burial in Littoral Waters/Coastal Morphodynamics
Over the past fifteen years, we have conducted research on mine burial in surf and shoaling zones in support of Navy’s mine countermeasures efforts. The major approach was laboratory experiments with a long wave tank that has a movable (sandy) bottom. Complementary numerical and theoretical work was also conducted. Our research has been incorporated to the Mine Burial Expert System developed by APL/JHU for the Navy. We have also conducted research on littoral ripples, in support of the SAX-04 experiment. Ocean Measurements
Through the support of the Office of Naval Research, we have conducted internal-waves, turbulence and circulation measurements in the East China Sea (Figure 3), with applications to ocean acoustic scattering and circulation modeling. In an earlier study, CTD and turbulence structures were also mapped in several trans-Atlantic cross sections. The aim was to investigate the effects of ocean bottom topography on benthic boundary layer properties, internal waves and turbulent exchange processes. The latter determine eddy coefficients at various oceanic layers. While previous measurements were done with loaned instruments, we are in the process of acquiring an array of instruments, including ADV, ADCP and microstructure profilers.
We employ a suite of instruments (Doppler Lidars, sodars, RASS, Ceilometers, IR Cameras, sonic anemometers and tethered balloons) for atmospheric measurements (Figure 4). Recently we developed a technique in which a combination of hot-film and sonic anemometry is used in an automated mode to measure a broad spectrum of scales in boundary-layer turbulence. Our expertise with diverse instruments that can interrogate a range of scales is extremely useful in energy and air pollution research. We also employ Dustracks for aerosol measurements

For the past ten years, we have conducted extensive meteorological and air quality modeling for the State of Arizona. The modeling tools used consist of MM5, WRF, WRF-CHEM, CMAQ, CALPUFF, CALMET and QUIC models. In addition, we have developed a special urbanized version of MM5, which is available for such studies as urban heat island, contaminant dispersion and pollution mitigation. Our computational work uses nested modeling from synoptic to pedestrian scales, through downscaling via mesoscale and CFD models (Figures 5). We have also developed our own CFD code for flow and dispersion calculations.

Industrial Fluid Mechanics
Our expertise encompasses numerous industrial problems, and our approach includes the use of smaller test facilities for rapid investigations and the use of Computational Codes such as FLUENT for detailed flow calculations. Some on-going projects include research on air entrainment to side branch lines of the Palo Verde Nuclear Power Generating Station and experimental and numerical (FLUENT) simulation of convection in Strategic Petroleum Reserves (for Sandia National Laboratories); see Figure 6.
