The flow around a stalled airfoil is investigated using zonal detached-eddy simulation (mode 2), including transition effects through a coupling with the [Formula: see text] framework. The airfoil exhibits mixed trailing edge-leading edge stall type properties. The chord length-based Reynolds number and Mach number, respectively, amount to [Formula...
Granular materials segregate spontaneously due to differences in particle size, shape, density and flow behaviour. In this paper we experimentally investigate density-difference-driven segregation for a range of density ratios and a range of heavy particle concentrations. The experiments are conducted in an annular shear cell with rotating bumpy bo...
This article intends to revisit the electro-diffusional theory for the wall shear stress measurement from mass transfer probes of rectangular shape by considering the existence of two components of the wall shear rate (i.e., axial and transversal). General analytical formulas for the effective transfer length and the dimensionless mass transport co...

The interface bond between layers plays an important role in the behavior of pavement structure. However, this aspect has not yet been adequately considered in the pavement analysis process due to the lack of advanced characterizations of actual condition. In many pavement design procedures, only completely bonded or unbounded interfaces between th...
Une structure massive en béton posée sur un soubassement en béton via des appareils d'appui néoprène a été renforcée en insérant des aciers passifs traversant les deux structures de béton. Le gestionnaire de l'ouvrage voudrait connaître la résistance réelle de ce renforcement en cas de séisme.

The aim of this work is to discuss the importance of the time-dependent shear forces in long span bridges built by the cantilever method, mainly in the connection sections between cantilevers when hinge devices exist. The approach considers the time-dependent properties of concrete and prestressing steel towards a simplified model able to rapidly e...
