Liquid Precursor Plasma Spraying: Modeling the Interactions Between the Transient Plasma Jet and the Droplets

摘要: Plasma spraying using liquid feedstock makes it possible to produce thin coatings (<100 μm) with more refined microstructures than in conventional plasma spraying. However, the low density of droplets them very sensitive instantaneous characteristics fluctuating jet at location where they are injected. In this study, interactions between and explored by numerical simulations. The computations based on a three-dimensional time-dependent model that couples dynamic behaviour arc inside torch issuing from torch. turbulence develops flow air is modeled large Eddy simulation computes largest structures which carry most energy momentum.
