Abstract

High velocity oxygen-fuel (HVOF) thermal spraying is a relatively new technology compared to other protective coating methods. Powders sprayed by liquid fuel HVOF guns are able to achieve high impact velocities without overheating, which results in superior coatings. A computational fluid dynamic (CFD) model is developed to investigate propane combustion in the process of HVOF thermal spraying. The numerical methods are described for correct representation of various thermal-physical phenomena such as flame propagation, turbulent mixing and flow acceleration. The principal advantages and shortcomings of various models are discussed.
