Abstract: A Computational Fluid Dynamics Software was used to calculate the atomizing gasfields generated by a self-designed atomizer and to analyze the effects of key atomizingvariables such as gas pressure and protrusion length of delivery tube on the gas flowstate at the tip of or inside the delivery tube. Increasing the length of delivery tube toa certain extent, the eddy flow region with positive pressure moves away from the tipof delivery tube, which is favorable to achieve the effective atomization of the melt.
