| 在密炼机动环端面设计了一种特斯拉阀-螺旋槽复合织构，并通过Solidworks软件建立密封环（包括动环和静环）三维模型，分析在热-流-固耦合条件下介质温度、入口压力、动环转速对密炼机密封端面温度、应力、变形的影响。结果表明：随着介质温度的升高，动环端面螺旋槽堰区变形不断增大，静环端面在与动环螺旋槽与特斯拉阀之间的无织构区相对应位置的变形范围及变形量不断增大；随着入口压力的增大，动环端面螺旋槽堰区变形不断减小，静环端面变形则先减小后保持不变；随着动环转速的增大，动环和静环端面温度均呈明显的下降趋势，动环端面螺旋槽堰区变形不断减小，静环端面变形明显减小，应力不断增大。 |

| A Tesla valve-spiral groove composite texture was designed on the moving ring end-face of internal mixer.A three-dimensional model of the sealing rings included moving ring and static ring was established by using Solidworks software，and the effects of the medium temperatures，inlet pressures，and moving ring speeds on the temperatures，stresses and deformations of sealing end-faces of internal mixer under thermal-fluid-solid coupling conditions were analyzed.The results indicated that as the medium temperature increased，the deformation of the spiral groove weir zone of the moving ring end-face continued to increase，while the deformation range and amount at the position corresponding to the non-textured zone between the moving ring spiral groove and the Tesla valve on the static ring end-face continued to increase.As the inlet pressure increased，the deformation of the spiral groove weir area of the moving ring end-face continuously decreased，while the deformation of the static ring end-face first decreased and then remained unchanged.With the increase of the moving ring speed，the temperatures of both the moving and static ring end-faces showed a significant downward trend，while the deformation of the spiral groove weir area of the moving ring end-face continued to decrease，the deformation of the static ring end-face decreased significantly，the stress continuously increased. |
