In this paper we study existence and uniqueness of weak solutions for some non-linear weighted Stokes problems using convex analysis. The characteri- zation of these considered equations is that the viscosity depends on the strain rate of the velocity fiel ...
Drop-on-demand inkjet printing is mostly based on thermal and piezo-actuation, allowing for densely packed nozzles in inkjet printers. However, the droplet diameter is typically defined by the nozzle diameter, thus limiting the range of viscosity that can ...
Liquid films flowing down the underside of inclined plates are subject to the interaction between the hydrodynamic and the Rayleigh-Taylor (R-T) instabilities causing a patterned and wavy topology at the free surface. The R-T instability results from the d ...
Being able to accurately reproduce the physiological phenomena which take place in blood vessels requires understanding the impact physical parameters have on the fluid’s flow. Modeling blood flow implies choosing, or defining, at least one model with the ...
The aim of the present paper is to contribute to the identification of the principal mechanical- hydraulical relationships du ring hydraulic transients by means of the analysis of observed transient pressure and strain waves in different pipe rigs. Four di ...
Locomotion is an essential feature for survival of many organisms, and it is also a technical requirement for untethered biomedical microdevices to operate inside the human body for targeted drug delivery and minimally invasive surgery. The overall goal of ...
The objective of this project is the fabrication of hollow piezoelectric micro electric mechanical systems (PZE-MEMS) arrays with suspended micro-channels integrated with a microfluidic network. The ultimate goal is to demonstrate the feasibility of charac ...
It is generally accepted that low and oscillatory wall shear stress favors the initiation and development of atherosclerosis. However, a quantitative analysis of the association between shear stress metrics at baseline and lesion prevalence at a later stag ...
Geologic carbon storage is considered to be one of the main solutions to significantly reduce CO2 emissions to the atmosphere to mitigate climate change. CO2 injection in deep geological formations entails a two-phase flow, being CO2 the non-wetting phase. ...
A precise knowledge of co-axial flow dynamics and a better understanding of the mechanisms that act to destabilize the interface between the two fluids is of fundamental interest in many industrial applications like lubricated transport, injection devices, ...
