Full-volume three-component intraventricular vector flow mapping by triplane color Doppler
Florian Vixège, Alain Berod, Pierre-Yves Courand +5
Intraventricular vector flow mapping (iVFM) is a technique for retrieving 2-D velocity vector fields of blood flow in the left ventricle. This method is based on conventional color…
Physics-constrained intraventricular vector flow mapping by color Doppler
Florian Vixège, Alain Berod, Yunyun Sun +6
Color Doppler by transthoracic echocardiography creates 2-D fan-shaped maps of blood velocities in the cardiac cavities. It is a one-component velocimetric technique since it only…
A new look at blood shear-thinning
Luca Lanotte, Johannes Mauer, Simon Mendez +6
Blood viscosity decreases with shear stress, a property essential for an efficient perfusion of the vascular tree. Shear-thinning is intimately related to the dynamics and mutual i…
Stability analysis of thermo-acoustic nonlinear eigenproblems in annular combustors. Part II. Uncertainty quantification
Luca Magri, Michael Bauerheim, Franck Nicoud +1
Monte Carlo and Active Subspace Identification methods are combined with first- and second-order adjoint sensitivities to perform (forward) uncertainty quantification analysis of t…
On the damped oscillations of an elastic quasi-circular membrane in a two-dimensional incompressible fluid
Marco Martins Afonso, Simon Mendez, Franck Nicoud
We propose a procedure - partly analytical and partly numerical - to find the frequency and the damping rate of the small-amplitude oscillations of a massless elastic capsule immer…
Elucidating the turbulence nature of the intracardiac flow: from medical images to multi-cycle Large Eddy Simulations
Christophe Chnafa, Simon Mendez, Franck Nicoud
This brief article accompanies a fluid dynamics video presenting the results of a large-eddy simulation of the flow in a realistic left heart. The left heart geometry, from the pul…
