摘要：
A numerical solution of the momentum and energy equations yields steady flow and temperature fields within a melt spinning puddle. The model accounts for inertial. viscous, surface tension, and wetting effects, and relies on a temperature-dependent viscosity to solidify ribbon to an amorphous state. A reference simulation is presented, followed by results that examine the effect of varying individual parameters. Results demonstrate a strong influence of nozzle wetting on puddle size: significant recirculation upstream of the nozzle slot: and the presence of both recirculation and an unrelated bump downstream of the slot.
