Papers presented at the AVT-169 RTO AVT/VKI Lecture Series held at the von Karman Institute, Rhode St. Genese, Belgium, 9-12 February 2009.
These Lecture Series proceedings are especially dedicated to the numerous topics arising when researchers have to predict numerically the behaviour of nanoparticles in a fluid. Beside an isolated nano object, the keyword of nanoparticle has to be understood more generally as including also agglomerate of nanoparticles, of nano-tubes and/or related complex structures.
As a matter of fact, numerous questions arise when the formation and the path of such objects have to be numerically predicted. Already concerning the methodology, the researchers have to select a Lagrangian or an Eulerian framework for the models development. The applicability of some of these models may be questionable when the diameter of the nanoparticles is comparable to the local molecular mean free path. In other words, it may be crucial to choose between a continuous and a non-continuous approach.
These two important issues are presented in the proceedings together with many others such as a detailed introduction to the Method of Moments with Interpolative Closure (MOMIC). It is shown how this method may be combined with the Dynamic Monte Carlo (DMC) technique allowing the study of nanoparticles aggregation. MOMIC, DMC and atomistic modeling allow also studying the particle formation from its nucleation including the particle surface growth.
These Lecture Series proceedings also include a complete description of the multi-fluid formulation extracted from the Kinetic theory with details on different models such as the one describing coalescence. The transport, deposition and removal of charged nanoparticles are also investigated together with a full detailed presentation of the static and the dynamic electrorheology approach. The sintering process of nanoparticles is presented in the frame of stochastic particle method and applied to the soot formation. The transport properties of plasma flows are reviewed in order to better understand the nanoparticle synthesis from a plasma reactor. This approach uses an efficient quench in order to condense the chemical species in a cloud of nanoparticle nucleus.
All these advanced models, methods and techniques are presented and detailed by a panel of distinguished authors worldly recognized for their contributions in numerical models for nanoparticles in fluids.
