Figure 8
The advection of oscillating harmonics in carotid waveform cannot be correlated with the mean flow velocity as long as \(\frac{\tilde{u}}{U}>1\), hence, it is not possible to obtain the energy field in wavenumber domain. (a) The carotid waveform at varying distance from the wall is plotted against dimensionless time and the red dashed line depicts the mean flow velocity. The flow near the wall is more complex than such away from the wall. (b) Colourmap of the velocity field of one cycle plotted against distance from the wall. (c) Colourmap of \(\frac{\tilde{u}}{U}\) plotted against distance from the wall.
