Abstract

This paper investigates three different types of nozzle geometries and the first steps for individual shape optimization to maximize the powder impact velocities. The basic types concern (i) a convergent, (ii) a convergent-divergent, and (iii) a convergent-constant geometry. For each nozzle type, four geometrical variables were investigated to reveal their individual and possibly combined potential to improve particle impact velocities.
