Abstract

The paper presents a theoretical analysis of the flame spraying with an independent source of cocurrent flow. The spraying process is represented by "three-layer model", describing the motion of a two-phase jet in cocurrent flow. For the numerical simulation of two-phase turbulent flows used k-ε turbulence model by Londer-Jones. To determine the required velocity of the particles in the flame were calculated necessary velocities of cocurrent flow.

Keywords flame spraying, cocurrent flow, interaction modeling, particle velocity
