    • Close pairs of relative equilibria for identical point vortices 

      T. Dirksen; Aref, Hassan (American Institute of Physics, 2011-05-01)
      Numerical solution of the classical problem of relative equilibria for identical point vortices on the unbounded plane reveals configurations that are very close to the analytically known, centered, symmetrically arranged, ...
    • The Dynamic Character of the Flow Over a 3.5 Caliber Tangent-Ogive Cylinder in Steady and Maneuvering States at High Incidence 

      Zeiger, Matthew D. (Virginia Tech, 2014-01-27)
      Although complex, inconsistent and fickle, the time-averaged flow over a stationary slender forebody is generally well-understood. However, the nature of unsteady, time-varying flows over slender forebodies - whether due ...
    • Geometry induced flow disturbances 

      Yazdani, Saami Kaveh (Virginia Tech, 2003-09-19)
      From clinical studies it is well known that atherosclerosis has preferred locations in the vascular system, primarily sited in the carotid arteries, coronary arteries, and in vessels supplying the lower extremities in the ...

    • The role of large-scale vortical structures in transient convective heat transfer augmentation 

      Hubble, David O.; Vlachos, Pavlos P.; Diller, Tom E. (Cambridge University Press, 2013-03-01)
      The physical mechanism by which large-scale vortical structures augment convective heat transfer is a fundamental problem of turbulent flows. To investigate this phenomenon, two separate experiments were performed using ...
    • Stability of relative equilibria of three vortices 

      Aref, Hassan (American Institute of Physics, 2009-09-01)
      Three point vortices on the unbounded plane have relative equilibria wherein the vortices either form an equilateral triangle or are collinear. While the stability analysis of the equilateral triangle configurations is ...
