in this paper, direct numerical simulation of two-phase incompressible gas-liquid flow for simulation of bubble motion in a microtube is presented. microtube radius is 10 µm. the interface is tracked using volume of fluid (vof) method with continuous surface force (csf) model. the flow is solved using a finite volume scheme, based on piso algorithm. numerical simulation is performed on a axisym...

Abstract In the context of deep geological disposal nuclear waste and to improve understanding homogenisation process bentonite barriers, in particular with regard filling technological voids, tests were performed compacted FEBEX samples hydrated under limited axial swelling conditions. The saturated from top surface using vapour transfer technique (imposing suctions 6 0.5 MPa), or deionised wa...

Copper electrodeposition in high-aspect-ratio through-holes micromachined by deep reactive ion etching is one of the most essential processes for fabricating through-wafer interconnects, which will be used in developing future generation high-speed, compact 3D microelectronic devices. Although copper electrodeposition is a well-established process, completely void-free electroplating in very de...

This laboratory investigation has been conducted to elucidate how the fi nes fraction affects the undrained residual shear strength and liquefaction potential of sand-silt mixtures (Algeria). A series of monotonic and cyclic undrained triaxial tests were carried out on undrained, reconstituted, saturated samples of sand with varying fi nes content ranging from 0 to 50%. These were undertaken in...

AIMS We assessed regulation of volume-sensitive Cl(-) current (I(Cl,swell)) by endothelin-1 (ET-1) and characterized the signalling pathway responsible for its activation in rabbit atrial and ventricular myocytes. METHODS AND RESULTS ET-1 elicited I(Cl,swell) under isosmotic conditions. Outwardly rectified Cl(-) current was blocked by the I(Cl,swell)-selective inhibitor DCPIB or osmotic shrin...

there are limitations in experimental studies on sand-gravel mixtures due to the small size of testingspecimens. due to this problem, many researchers have worked on prediction of the shear strength of mixture by testingthe sandy fraction of soil alone and developed empirical relationships. most of the previous relationships have beendetermined for low surcharge pressures in which particle brea...
