Propagation of a Radial Fluid-driven Fracture in Nonlinear Solid --around the tip of a fluid-driven fracture: process zone vs deviated fluid flow

Brice Tanguy Alphonse Lecampion, Dong Liu

Deviations from conventional hydraulic fracturing simulators’ predictions are sometimes observed in the field and laboratory. This questions the basic assumptions adopted in linear hydraulic fracture mechanics (LHFM): a linear elastic solid and a simplifie ...

We use the Carreau rheological model which properly accounts for the shear-thinning behaviour between the low and high shear rate Newtonian limits to investigate the problem of a semi-infinite hydraulic fracture propagating at a constant velocity in an imp ...

Production of monodisperse drops from viscous fluids

Esther Amstad, Mathias Steinacher, Tomasz Radoslaw Szymborski, Armend Gazmeno Hati

Drops are often used as picoliter-sized reaction vessels, for example for high-throughput screening assays, or as templates to produce particles of controlled sizes and compositions. Many of these applications require close control over the size of drops, ...

Suspended Microchannel Resonators (SMRs) are hollow resonant structures containing an embedded U-shaped microfluidic channel. Theoretical and experimental results have proved that in these devices the energy dissipation is a non-monotonic function of the f ...

We analyze the dynamic behavior of Newtonian fluids in elastic tubes subject to pulsatile pressure gradients and show that the interplay between the viscosity of the fluid, the elasticity of the wall, and the characteristic size of the confining media give ...

Energy dissipation in hollow beam resonators in function of microfluidic channel off-axis placement

Annalisa De Pastina, Mauricio Lucena Couto

Suspended Microchannel Resonators (SMRs) are hollow resonant structures containing an embedded u-shaped micro fluidic channel. Having the sample fluid confined inside the resonator allows for real time detection of liquid compounds while the device quality ...

Effect of fluid viscosity on fault frictional behavior

Marie Estelle Solange Violay, Chiara Cornelio

Tectonic faults are often lubricated by viscous fluids which can have different natures e.g. gas, water, brine, melt and viscosities varying over 7 order of magnitude (from 10-4 for water to 103 Pa s-1 for a melt at high temperature). Moreover, understandi ...

Fluid-structure interaction for vascular flows: From supercomputers to laptops

Simone Deparis, Davide Forti, Claudia Maria Colciago

Several models exist for the simulation of vascular flows; they span from simple circuit models to full three-dimensional ones that take into account detailed features of the blood and of the arterialwall. Eachmodel comeswith both benefits and drawbacks, t ...

Understanding fluids viscosity effects on fault dynamics can shed light on the induced seismicity in engineering reservoirs where fluids with viscosity ranking from 1mPa s-1 to 1000 mPa s-1 are also injected during hydraulic fracturing process in order to ...

Suspended Microchannel Resonators (SMRs) enable real time analysis of fluidic samples with almost no degradation of the quality factor. - Energy dissipation is a non-monotonic function of the fluid viscosity. - Quality factor is highly dependent on the mic ...
