The present study aims to examine the characteristics of flow with respect to various fuel conditions in the flame spray coating process. The flame spray flow is characterized by very complex phenomena including combustion, turbulent flows, and convective and radiative heat transfer. In this study, we simulated flame spray process by using a commercial computational fluid dynamics (CFD) code of FLUENT (ver. 13.0) to predict gas dynamics involving combustion, gas temperature and velocity distributions. Also, we examined the effect of type of fuel and equivalence ratio on the flame spray process. It was found that axial gas temperature increased from initial temperature to maximum temperature while flame goes to the substrate because fuel reacts additionally to oxygen in the air in radial direction.
