“…Zhuang and al. [8] have estimated the dimensions of the task of zirconium particles impact on the substrate projected by hydrogen-nitrogen plasma jet under openair conditions. The model is based on the resolution of the corresponding continuity, momentum, energy and mass conservation equations of the gas plasma, and plasma-particle.…”

“…It is difficult to describe the behavior during the impact on the substrate which is directly related to the thermal and dynamic particle histories in the flame. This dynamic and thermal behavior is described by numerical simulations to independently evaluate the axisymmetric jet flow and the particle behavior injected into it [6][7][8][9][10][11][12]. This study is conducted to demonstrate the effects of various pertinent parameters on the fluid flow and heat transfer characteristics.…”

Numerical simulation of the interaction between the spherical particle and plasma gas is carried out. The aim of this study is to investigatethermal transfer between the plasma gas and solid particle during the plasma spray process and to validate the well-known empirical correlation of the Ranz and Marshall. In the conditions of molten or semi-molten states of prepared substrate, the medium (plasma jet) can affect the high velocities of particles. On the basis of direct numerical simulation, the computational analysis has been carried out by using computational fluid dynamics (CFD) of heat transfer in atmospheric pressure and mid-temperature range (3000k–12000k) of a plasma flow over a spherical particle. Our proposed model improves correlation with experiments compared to the existing approaches in the literature.

A three-dimensional simulation of the thermal plasma spraying process is reported. In particular, the effect of the radial injection of a carrier gas is taken into account for a dilute spray. The thermal history of powder particles of different sizes is predicted. It is shown that introduction of a carrier gas can lead to a significant modification of the plasma jet, and can have an effect on the thermal histories of the injected particles. The study is motivated by the processing of non-traditional materials, specifically nanostructured ceramics.
