Modeling and Computation of Nanoparticles in Fluid Flows (Modelisation et calcul des nanoparticules dans la circulation des fluides).

摘要

These Lecture Series was dedicated to numerical description of nanoparticles in a fluid. Different possible frameworks were reviewed including Lagrangian, Eulerian, continuous or non-continuous approach. A complete description of the Method of Moments with Interpolative Closure together with the Dynamic Monte Carlo technique combine with atomistic model allowed describing the nanoparticle formation from its nucleation to its aggregation. Review of alternative approach such as the multi-fluid formulation derived from the Kinetic theory is done. A complete description of electrostatic effect including the transport, deposition and removal of charged nanoparticles plus the static and the dynamic electrorheology presentation are done. Many other advance processes including the sintering phenomenon treated with the stochastic particle method and applied to the soot formation are proposed. The transport properties of plasma flows are reviewed in order to better understand the nanoparticle synthesis from a plasma reactor. Among other this synthesis must use an efficient quench in order to condense the chemical species in a cloud of nanoparticle nucleus.
