  • Bhattacharjee, Pratik; Riahi, Daniel N. (Department of Theoretical and Applied Mechanics (UIUC), 2003-02)
    Effect of rotation on nonlinear solutal convection during protein cystallization is modelled and studied computationally under both normal and microgravity conditions. The axis of the externally imposed rotation, which is ...

  • Bagchi, Prosenjit; Balachandar, S. (Department of Theoretical and Applied Mechanics (UIUC), 2002-10)
    A direct numerical simulation (DNS) is used to study the effect of a freestream isotropic turbulent flow on the drag and lift forces on a spherical particle. The particle diameter is about 1.5 to 10 times the Kolmogorov ...

  • Phillips, W.R.C. (Department of Theoretical and Applied Mechanics (UIUC), 2001-11)
    Langmuir circulations in the open ocean typically form in an environment of surface waves and a shear current, and a mechanism which exploits these features and leads to shear-aligned longitudinal vortices much like Langmuir ...

  • Christensen, Kenneth T.; Adrian, Ronald J. (Department of Theoretical and Applied Mechanics (UIUC), 2001-12)
    Acceleration is a fundamental quantity in fluid mechanics because it reflects the sum of all forces (pressure and viscous) present within the flow. However, measurements of acceleration have been difficult to achieve ...

  • Riahi, Daniel N. (Department of Theoretical and Applied Mechanics (UIUC), 2003-06)
    The topic of this review article is about some aspect of flow during alloy solidification and the corresponding research development that has been accomplished in the recent years to determine the features of such flows, ...

  • Adrian, Ronald J.; Balachandar, S.; Liu, Zi-Chao (Department of Theoretical and Applied Mechanics (UIUC), 2001-09)
    Recent studies of the structure of wall turbulence have lead to the development of a conceptual model that validates and integrates many elements of previous models into a relatively simple picture based on self-assembling ...

  • Tomkins, Christopher D.; Adrian, Ronald J. (Department of Theoretical and Applied Mechanics (UIUC), 2002-08)
    Spanwise structure and growth mechanisms in a turbulent boundary layer are investigated experimentally. PIV measurements are obtained in the streamwise–spanwise (x–z) plane from the buffer layer to the top of the logarithmic ...

    The transition to turbulent flow is studied for liquids of different polarities in glass microtubes having diameters between 50 and 247 µm. The onset of transition occurs at Reynolds number ~1800–2000, as indicated by ...
