Three Dimensional Modeling of the Plasma Spray Process
He-Ping Li,Emil Pfender +1 more
TL;DR: In this paper, the results of simulations of a DC arc plasma torch in steady state with transverse particle and carrier gas injection into the plasma jet are presented, showing that an increase of the gas flow rate at constant current moves the anode arc root further downstream leading to higher enthalpy and velocity at the exit of the torch anode, and stronger mixing effects in the jet region.

Liquid Precursor Plasma Spraying: Modeling the Interactions Between the Transient Plasma Jet and the Droplets
TL;DR: In this article, the interactions between the fluctuating plasma jet and droplets are explored by using numerical simulations based on a three-dimensional and time-dependent model of the plasma jet.
Journal ArticleDOI
Three-Dimension and Transient D.C. Plasma Flow Modeling
TL;DR: In this article, the behavior of plasma flow generated by a D.C. plasma spraying gun is simulated in a time-dependent 3D design, where the criterion of validation is the thermal efficiency while the only adjustment parameter is the length of the plasma column inside the anode.

Plasma Spraying: From Plasma Generation to Coating Structure
Pierre Fauchais,G. Montavon +1 more
TL;DR: In this article, the authors discuss the mechanism and thermodynamic chemistry involved in the plasma spraying process, focusing on the mechanism of adhesion between the coating and the substrate and on the cohesion between deposited layers.

Boundary layer theory
TL;DR: The flow laws of the actual flows at high Reynolds numbers differ considerably from those of the laminar flows treated in the preceding part, denoted as turbulence as discussed by the authors, and the actual flow is very different from that of the Poiseuille flow.

Convection Heat Transfer
TL;DR: In this paper, the authors describe a transition from Laminar boundary layer flow to Turbulent Boundary Layer flow with change of phase Mass Transfer Convection in Porous Media.

Enhancements of the simple method for predicting incompressible fluid flows
J. P. Van Doormaal,G. D. Raithby +1 more
TL;DR: The performances of SIMPLE, SIMPLER, and SIMPLEC are compared for two recirculating flow problems and several modifications to the method are shown which both simplify its implementation and reduce solution costs.

A Viscosity Equation for Gas Mixtures
TL;DR: In this paper, the previous equation of Buddenberg and the author has been modified to give a general equation for viscosity as a function of molecular weights and viscosities of the pure components of the mixture.
