Transitional and turbulent rotating flows appear in geophysics and astrophysics and in many industrial devices. In the rotating flows the momentum transfer mechanism is highly complicated and the understanding of this process is of great importance for engineers as well as for fundamental research. The overall objective of the project is to investigate experimentally (PIV 2D3C/LDA - CoGeof2b) and numerically (DNS/SVV – direct numerical simulation/spectral vanishing viscosity method) the dynamics of the vortices in the rotating cavities. To reach this purpose, the authors will investigate the flow in the rotor/stator cavity of different aspect ratios. The authors believe that combined experimental/numerical investigations can help to obtain the answer to the questions concerning transitional and turbulent flow structures, their origins and their role in creating stress.
