Numerical simulation of bubble generation in a T-junction [PDF]

, 2012
We present a numerical study of the formation of mini-bubbles in a 2D T-junction by means of the fluid dynamics numerical code JADIM. Numerical simulations were carried out for different flow conditions, giving rise to results on the behavior of bubble ...

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 ...

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.

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 ...

Mechanical Loading Dependence on Burning Surface Areas

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 5, May 2025.
ABSTRACT The transition from normal (surface) to abnormal (convective) burning modes of explosives is still a difficult phenomenon to model. This transition, which yields the acceleration of the combustion propagation, could result in a violent reaction. Nowadays, abnormal burning is interpreted as an increase in burning surface area.

Modélisation et caractérisation expérimentale d'un échangeur à plaque d'une VMC [PDF]

, 2012
International audienceABSTRACT. In this paper, we model a heat exchanger of a mechanical ventilation system. The model uses the ε-NTU approach and takes into consideration the phenomenon of condensation on the cooled air side.
