摘要

气体夹杂物会严重影响凝固熔体的质量。由于扩散和化学反应，液态金属中的溶解气体有助于新夹杂物的形成和生长。球形空腔动态行为的数学问题采用纳维-斯托克斯方程求解，将熔体视为粘性不可压缩流体。得出了在熔体的牛顿行为下球形空腔半径变化的表达式。

On the motion of a spherical cavity in a melt

Gas inclusions significantly influence the quality of solidifying melts. Dissolved gases in liquid metals, due to diffusion and chemical reactions, contribute to the formation and growth of new inclusions. The mathematical problem of the dynamic behavior of a spherical cavity is solved using the Navier‑Stokes equation, treating the melt as a viscous incompressible fluid. An expression for the change in radius of a spherical cavity under Newtonian behavior of the melts is obtained.
