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...

In this paper, the lift-law method was applied to design the axial flow pump. Based on Reynolds time-averaged N-S equations and standard k turbulent model, three-dimensional air-water bubbly flow in an axial flow pump impeller was simulated. Under the condition of bubble void fraction of 5%, pressure and void fraction distributions were respectively obtained, movement of bubbles in the impeller...

In this study, the authors hypothesized that in acute ischemic strokes, more permeable intracranial arterial thrombi (as opposed to less permeable thrombi) could be associated with better clinical outcomes and improved response to intra-arterial therapy. The authors examined the attenuation increase on computed tomographic angiography (CTA) and void fraction, using combination of noncontrast co...

Use of X-ray CT (Computer Tomography) system has been extended from medical fields to a variety of industrial applications [1, 2]. Among them is the visualization of multi-dimensional void distribution of two-phase flow in tubes. Mitsutake et al. [3] and Morooka et al. [4] used medical X-ray CT scanners modified for void fraction measurement within rod bundles. The results were comparable with ...
