Abstract: The shear modulus of two-dimensional liquid foams in the dry limit of low liquid content has been studied theoretically. The focus is on the effect of geometrical disorder on the shear modulus ...

Abstract: Various theories exist for predicting the pressure on the walls of bins filled with granular material. These theories, such as Janssen’s (1895) theory, usually neglect the effect of the ...

Abstract: In order to develop constitutive relations for granular materials from the micromechanical viewpoint, general expressions relating macroscopic stress and strain to contact forces and particle ...

Abstract: The hydraulic performance of an industrial mixed-flow pump is analyzed using a three-dimensional potential flow model to compute the unsteady flow through the entire pump configuration. Subsequently, ...

Abstract: Two-dimensional particle image velocimetry measurements and three-dimensional computational fluid dynamics (CFD) analyses have been performed on the steady velocity field inside the shrouded impeller ...

Abstract: To increase the understanding of complex flows in dredging cutter heads, an experimental and numerical investigation of these flows has been made. As a first step toward the investigation of the mixture flow in a complete ...
