Abstract
The left ventricle (LV) flow dynamics was reproduced in a laboratory model, and three dimensional velocity fields were reconstructed from two dimensional image analysis measurements on two sets of orthogonal planes. The flow features were investigated by means of Finite Time Lyapunov exponents (FTLE), a Lagrangian based methodology useful to assess Lagrangian Coherent Structure (LCS) time evolution and flow mixing properties.| File | Dimensione | Formato | |
