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…

From ship loader to port city. The case of Porto Empedocle (Da caricatore a città portuale. Il caso di Porto Empedocle)

2014

Porto Empedocle was, for many centuries, the port of the nearby city of Agrigento, imposing itself for exceptional locational qualities as maritime crossroads between all the seaports on the south coast of Sicily, albeit with ups and downs. Thanks to its strategic location, facing the north African coast and connections to the inner areas, the simple warehouse and provisioner became crucial for the economy of the island so as to be called the "most active warehouse and provisioner of the kingdom". Were performed a series of measures aimed at achieving real port facilities which would transform the original glade in functional landing place for boats of any size. Due its history, Porto Emped…

La città di Alphabet. Architettura per prosumers.

2021

Attraverso alcuni aspetti salienti dell’ideazione, della produzione e dell’opposizione al progetto del Toronto Quayside di Sidewalk labs, l’articolo discute l’influenza delle infrastrutture digitali per l’informazione sul progetto della casa e del quartiere. L’ampliamento delle attività svolte da remoto nello spazio domestico, enfatizzato dal quotidiano della pandemia da Covid 19, costituisce per gli oligopolisti planetari degli urban data come Alphabet un utile volano pubblicitario e un acceleratore. La fusione dei nuovi vessilli della tecnoemancipazione e della sostenibilità in ipotesi sperimentali che mirano a costruirsi sia per intero che per parti realizza un nuovo orizzonte in cui lo …

Settore ICAR/14 - Composizione Architettonica E UrbanaTaking into account some salient aspects of the conception production and opposition to the Toronto Quayside project by Sidewalk labs the article discusses the influence of urban data-digital infrastructures on the architectural design of the house and the neighbourhood. The extension of remote control on the practices of everyday life in the domestic space emphasized by the daily Covid 19 pandemic constitutes a useful advertising reference and an accelerator for the planetary oligopolists of urban data such as Alphabet. The fusion of the new emblems of techno-emancipation and sustainability in experimental hypotheses that can be built both in whole or in parts draws a new horizon in which the domestic space generates a technological profit and the inhabitants are transformed into producers. From a historical perspective our reality eclipses the idea of technology as an anonymous contribution to collective progress demonstrated by Giedion in Mechanization takes command and subverts the allegorical value assigned by the Architecture of the Seventies to the relational utopias of the Web Stem and Cluster.

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…
