Cardiovascular diseases are the leading cause of death worldwide. In the United States, coronary artery disease accounts for 1 in 7 cardiovascular deaths. Cells in the blood and blood vessels are known to respond to alterations of the mechanical forces of their environment, such as blood ... En savoir plus

This study models the energy harvesting reached from an air flow transportation through the flapping of a cantilever polymer flag. The mechanical resonance of the flag is created by a Venturi channel. The flag is charged by triboelectrification and its flapping between two electrodes ... En savoir plus

The mechanical characterization of certain cell types is important to obtain physiological insights. For instance, tumor and normal cells can be distinguished by elasticity, indicated by the amount of deformation under given stress. Simulations help to understand, verify and improve the ...

Peristaltic pumps are used during pharmaceutical manufacturing processes, for filling, filtration and mixing operations. Goal of this work was to develop a computational model of a peristaltic pump used for filling operations, to predict shear stresses and mass flow rates. For this ... En savoir plus

Motivation We simulate the fluid driven interaction between two dynamically coupled valves designed to work in conjunction with each other. Such interacting valves are extensively used in sucker rod pumps for oil extraction. These pumps essentially consist of a pair of ball check valves ... En savoir plus

Biodegradable scaffolds are often inserted in the body, to provide mechanical support to recovering broken or damaged tissues. Monitoring the degradation chemistry and mechanical response of these scaffolds is important: their degradation rate should match tissue regeneration rate, while ... En savoir plus

The Eustachian Tube (ET) is a collapsible tube that connects the middle ear to the nasopharynx. Dysfunction in the ET leads to a disease called Otitis Media. Our goal is to develop and use fluid-structure interaction (FSI) models of ET opening phenomena to better understand what factors ... En savoir plus

The use of impellers is extremely widespread across various industrial applications. Fluid motion, mixing processes, and propulsion are just a few of the fields in which impellers play a key technological role. In general, impellers enable energy transfer through the interaction between ... En savoir plus

Passive, one-way valves, also known as check valves, while common at the macro scale, are an essential microfluidic feature that facilitate flow rectification. These structures are also commonly used in reciprocating micropump configurations to control flow. Their operation can be ... En savoir plus

The lymphatic system plays a crucial role in immune surveillance, fluid balance, and the transport of immune cells. Lymph nodes, acting as filtration and immune activation hubs, are essential in detecting and responding to pathogens. Computational modeling of lymph node function offers ... En savoir plus
