Vibrational Heat Transfer Intensification in an Annulus with a Deformable Boundary

Figure 2

Vector plots of steady-flow velocity fields at the heating power  W in the absence of vibrations (a) and at vibrations with the frequency and the amplitude (). (b) The colour maps represent vorticity calculated from the vector field of the time-average steady velocity. Below the inner cylinder, a shadow is seen.
