    • Extensive Chaos in The Lorenz-96 Model 

      Karimi, A.; Paul, Mark R. (AIP Publishing, 2010-12-01)
      We explore the high-dimensional chaotic dynamics of the Lorenz-96 model by computing the variation of the fractal dimension with system parameters. The Lorenz-96 model is a continuous in time and discrete in space model ...
    • Impulse and particle dislodgement under turbulent flow conditions 

      Celik, Ahmet Ozan; Diplas, Panayiotis; Dancey, Clinton L.; M. Valyrakis (American Institute of Physics, 2010-04-01)
      In this study, we investigated the role of turbulence fluctuations on the entrainment of a fully exposed grain near threshold flow conditions. Experiments were carried out to measure synchronously the near bed flow velocity ...
    • Three dimensional character of whistler turbulence 

      Ganguli, Gurudas; Rudakov, Leonid; Scales, Wayne A.; Wang, Joseph; Mithaiwala, Manish (AIP Publishing, 2010-05-01)
      It is shown that the dominant nonlinear effect makes the evolution of whistler turbulence essentially three dimensional in character. Induced nonlinear scattering due to slow density perturbation resulting from ponderomotive ...
    • Turbulence Measurements in Trailing Vortices for B.W.I. Noise Prediction 

      Devenport, William J.; Glegg, Stewart A. L.; Sharma, Gautam (Virginia Polytechnic Institute and State University, 1992-06-01)
      Blade wake interaction (BWI) noise is the broadband noise generated by the ingestion of turbulent tip vortices into helicopter rotors. Prediction of BWI noise requires knowledge of the turbulence structure of the tip vortex. ...
