| The effect of initial eccentric distance, substrate withdrawal velocity, spray angle and substrate shape on steady state behavior was studied, using 3 dimensional model of spray forming of rod by computer simulation. The mechanism to reach steady state at various conditions was analyzed through the growth velocity at vertex of rod, G_v. Above a critical eccentric distance, G_v, increased from the beginning of forming and reached steady state. Below a critical eccentric distance, G_v, decreased and reached steady state. Below a certain critical withdrawal velocity, the growth velocity of vertex reached steady state. .Above the critical value of withdrawal velocity, G_v, increased to critical value and decreased to zero growth velocity of vertex. The critical withdrawal velocity was the maximum velocity where spray axis coincide with vertex. |
