Urban sewer flooding:analysis of the behavior of drainage systems during extreme rain events
(2011)Currently cities and communities are experiencing ever growing problems related to urban pluvial flooding. This is due primarily to inefficient drainage inlets and overloaded sewer systems. In fact, existing drainage ... -
Coherent structures of turbulence in wall-bounded turbulent flows
(2011-10-24)Direct Numerical Simulation (DNS) of a fully developed turbulent channel flow represents a powerful tool in turbulence research: it has been carried out to investigate the main characteristics of wall-bounded turbulence. ... -
Preparation of Organic Solvent Resistant Polymeric Membranes for Applications in Non-aqueous Systems
(2011-11-08)Operazioni a membrana sono oggi usate in numerosi processi di separazione e il numero di applicazioni è in rapida crescita anche grazie alla necessità di sviluppare nuovi processi sempre più eco-sostenibili. Le operazioni ... -
Gold based photocatalysis used in the overall water splitting in a membrane reactor and in organic synthesis
(2011-11-08)La fotocatalisi eterogenea basata sull’utilizzo di catalizzatori di oro supportati si sta rivelando una tecnica promettente sia per la conversione di energia solare in energia chimica che per reazioni di sintesi organica, ... -
Synthesis and characterization of helically coiled carbon nanotubes
(2011-11-23)Although coiled carbon nanofibers can be synthesized on large scale, the selective synthesis of coiled carbon nanotubes is still a challenge for the scientific community. In the present work we aimed to produce helically ... -
Graphene and titanium based semiconductors in photocatalytic hydrogen and oxygen generation and hydrogenation of organics also in membrane reactors
(2013-11-12)The development of graphene (G)-based materials as photocatalysts has become in the last years of high interest due to their sustainability and flexibility in the modification and design, particularly in the field ... -
Development of membrane bioreactor (MBR) process applying novel low fouling membranes
(2013-11-12)Water is a part and parcel of human life. Water contaminated from industry and agriculture with heavy metal ions, pesticides, organic compounds, endocrine disruptive compounds, nutrients (phosphates, nitrates, nitrites) ... -
Simulating open-channel flows and advective diffusion phenomena through SPH model
(2014-04-11)The present thesis treats Computational Fluid Dynamics based on particle methods. The fully Lagrangian approach Smoothed Particle Hydrodynamics (SPH) is developed for two-phase flows. The model is extended to research ...
