Abstract:A simulation method was used to study the effects of physical parameters, including the contact angle between molten metal and material of orifice, surface tension and viscosity on particle formation of POEM. Stable droplets can be obtained only when the surface tension is adequate and the contact angle is at least 90 degrees or higher. Within a wide range, viscosity has little effect on droplet formation; as the viscosity increases, necking time is postponed and vibration time is shortened.
