H2020 NanoDome Project: A Unified Approach for Gas-Phase Nanoparticles Synthesis Modelling

Abstract

This article presents a unified physical mathematical approach to the modelling nanoparticles dynamic used by the Authors as a foundation to develop a software framework for modelling entities and phenomena occurring at mesoscopic length scale in a generic Gas-Phase (GP) nanoparticle synthesis processes (e.g. plasma, hot-wall and flame reactors) and using Gas-Phase parameters extracted from CFD simulation (linking process). The model considers nanoparticles motion, agglomeration and sintering phenomena and is aimed to provide detailed information about nanoparticles fractal dimension and composition, together with species concentration, consumption rates and particles size distribution. We provide a detailed description of the data structures, the numerical methods and the algorithms adopted to implement the simulation software based on this model.
