WebCFD. TKE was slightly higher for the motion-compensated waveform throughout the aor-tic arch. These results suggest that accounting for cardiac motion when quantifying blood flow through the AoV can lead to different conclusions for hemodynamic indices, which may be important if these results are ultimately used to predict patient outcomes. WebA better comparison would be between the total TKE of RANS and DES. Total TKE being modelled + resolved. There are resources online on how to calculate that, but you'll have to define field variables for those. If you do compare total TKE of RANS and DES, the RANS will probably still be higher, because it is transporting the modelled TKE ...
