This paper investigates flow patterns inside and outside the high-velocity oxy-fuel (HVOF) thermal spraying gun by aerodynamic experiments and one-dimensional analysis including wall friction (Fanno flow). In the experiments, static pressure along the barrel inner-wall is measured and schlieren pictures of jet discharged from the barrel exit are taken. The flow-fields predicted by the present simple analysis agree well with the experimental results. The present work shows that flow patterns of HVOF gun in operation depends on the stagnation pressure and barrel length.
