Computed Tomography (CT)-derived Cardiovascular Flow Estimation Using Physics-Informed Neural Networks Improves with Sinogram-based Training: A Simulation Study
Jinyuxuan Guo, Gurnoor Singh Khurana, Alejandro Gonzalo Grande +2
Background: Non-invasive imaging-based assessment of blood flow plays a critical role in evaluating heart function and structure. Computed Tomography (CT) is a widely-used imaging…
Reduced-order models of wall shear stress patterns in the left atrial appendage from a data-augmented atrial database
Jorge Dueñas-Pamplona, Sergio Rodríguez-Aparicio, Alejandro Gonzalo +8
Background: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, affecting over 1% of the population. It is usually triggered by irregular electrical impulses…
Self-organized mechano-chemical dynamics in amoeboid locomotion of Physarum fragments
Shun Zhang, Robert D. Guy, Juan C. Lasheras +1
The aim of this work is to quantify the spatio-temporal dynamics of flow-driven amoeboid locomotion in small (100 m) fragments of the true slime mold \phys {\it polycephal…
Scaling of the energy spectra of wall-bounded turbulence
Juan C. del Alamo, Javier Jimenez, Paulo Zandonade +1
By using new results from direct simulations of turbulent channels at moderate friction Reynolds numbers (Retau <= 1900) and in very large numerical boxes, we examine the correctio…
DNS of the very large anisotropic scales in a turbulent channel
Juan C. del Alamo, Javier Jimenez
The large structures in the outer layer of turbulent wall flows are of great physical importance, because they contain a substantial fraction of the streamwise kinetic energy and o…
Flow of a viscous nematic fluid around a sphere
Manuel Gómez-González, Juan C. del Álamo
We analyze the creeping flow generated by a spherical particle moving through a viscous fluid with nematic directional order, in which momentum diffusivity is anisotropic and which…
The Large Scale Organization of Turbulent Channels
Juan C. del Alamo
We have investigated the organization and dynamics of the large turbulent structures that develop in the logarithmic and outer layers of high-Reynolds-number wall flows. These stru…
Direct numerical simulation of the very large anisotropic scales in a turbulent channel
Juan C. del Alamo, Javier Jimenez
Over the last decades the knowledge on the small scales of turbulent wall flows has experienced a significant advance, especially in the near-wall region where the highest producti…
Characteristics of scalar dispersion in turbulent-channel flow
Juan C. del Alamo, Javier Jimenez
The dispersion of a passive scalar by wall turbulence, in the limit of infinite Peclet number, is analyzed using frozen velocity fields from the DNS by our group. The Lagrangian tr…
Three-Dimensional Quantification of Cellular Traction Forces and Mechanosensing of Thin Substrata by Fourier Traction Force Microscopy
Juan C del Alamo, Ruedi Meili, Begoña Alvarez-Gonzalez +4
We introduce a novel three-dimensional (3D) traction force microscopy (TFM) method motivated by the recent discovery that cells adhering on plane surfaces exert both in-plane and o…
