Dracula : mécanique des fluides et roman des angoisses circulatoires

Glad!, 2018
The vampiric monster in Stoker’s Dracula epitomizes a threat coming from the margins, which happens to be related to the body. Indeed, anxious Victorian concerns persisting about different types of flow lead us to question the concrete visibility of ...

Subcycling Strategy for Finite‐Volume Updated‐Lagrangian Methods Applied to Fluid–Structure Interaction

International Journal for Numerical Methods in Engineering, Volume 126, Issue 11, 15 June 2025.
ABSTRACT In this article, we propose and investigate an explicit partitioned method for solving shock dynamics in fluid–structure interaction (FSI) problems. The method is fully conservative, ensuring the local conservation of mass, momentum, and energy, which is crucial for accurately capturing strong shock interactions.

Analysis of different hypotheses for modeling air–water exchange and temperature evolution in a tropical reservoir

Journal of Water and Climate Change
The present analysis shows that the most crucial parameter for a correct representation of the observed temperature behavior are the heat exchange coefficient and the wind.

Experimental Measurement Benchmark for Compressible Fluidic Unsteady Jet

Actuators, 2018
A benchmark of different measurement techniques is presented to characterize the dynamic response of a synthetic jet actuator working in compressible regime. The setup involves a piston-based synthetic jet, as well as the benchmarked measurements are hot-

MR Elastography for Classification of Focal Liver Lesions Using Viscoelastic Parameters: A Pilot Study Based on Intrinsic and Extrinsic Activations

Journal of Magnetic Resonance Imaging, Volume 61, Issue 6, Page 2525-2540, June 2025.
Background Intrinsic activation MR elastography (iMRE) uses cardiovascular pulsations to assess tissue viscoelastic properties. Applying it to focal liver lesions extends its capabilities. Purpose To assess the viscoelastic parameters of focal liver lesions measured by iMRE and compare its diagnostic performance with extrinsic MRE (eMRE) for ...

High‐Yield Bioproduction of Extracellular Vesicles from Stem Cell Spheroids via Millifluidic Vortex Transport

Advanced Materials, Volume 37, Issue 20, May 19, 2025.
Stem cell spheroids, produced via a high‐throughput microfabrication technique, are transported within a vortex generated at the outlet channels of a cross‐slot millifluidic chip. For Reynolds number exceeding 170–200, intermittent high shear stresses applied to each spheroid within the vortex trigger a massive release of biologically active ...

Simulation of Cavitating Flows in Diesel Injectors Simulation des écoulements en cavitation dans les injecteurs diesel

Oil & Gas Science and Technology, 2006
With a new two fluid model it is possible to carry out three-dimensional CFD calculations of cavitating flows in hydraulic components of Diesel injection systems. As model geometries a ball valve, a sac-hole nozzle and a one-hole nozzle have been used to

Velocity of long bubbles transported by a liquid in horizontal channel

Vietnam Journal of Mechanics, 2010
The influence of flowing liquid on the motion of long bubbles in horizontal channel is studied theoretically. The method of Benjamin (1968) is extended to the case of moving liquid: the liquid is inviscid, the surface tension is ignored and the liquid ...
