Figure 5
Kinetic energy cascade detects non-Kolmogorov kinetic energy transfer at frequencies higher than dominant frequency. In (a), the kinetic energy cascade obtained from the exact solution of Womersley flow of carotid artery are plotted at varying locations from the wall. Similar cascades are displayed for the carotid blood flow of two healthy volunteers at the artery center (b,d) and at \(\frac{1}{3}D\) away from the wall (c,e). The scaling of energy cascades is found to be (b,c) \(-\frac{7}{2}\) (d) \(-\frac{43}{10}\) (e) \(-\frac{27}{10}\).
