Safety appraisal and rehabilitation of a quay wall
2005
The case-history of a quay wall which went on the verge of collapse and was subsequently stabilised is reported in the paper. The main instability cause was the deepening of sea floor in front of the wall. Stabilising measures were selected taking into account the extreme sensitivity of the structure even to modest mechanical actions such those induced by construction equipment. They were implemented in successive stages specifically designed for avoiding critical stability situations. Frequent displacement measurements during work execution showed temporary marked increases of the rate of displacement. The stabilisation works were successfully completed and the quay was brought back into o…
Large eddy simulation of inertial particles dispersion in a turbulent gas-particle channel flow bounded by rough walls
2020
The purpose of this paper is to understand the capability and consistency of large eddy simulation (LES) in Eulerian–Lagrangian studies aimed at predicting inertial particle dispersion in turbulent wall-bounded flows, in the absence of ad hoc closure models in the Lagrangian equations of particle motion. The degree of improvement granted by LES models is object of debate, in terms of both accurate prediction of particle accumulation and local particle segregation; therefore, we assessed the accuracy in the prediction of the particle velocity statistics by comparison against direct numerical simulation (DNS) of a finer computational mesh, under both one-way and two-way coupling regimes. We p…
