谈谈流体的阻力

ON DRAG FORCE OF FLUID

  • 摘要: 流体阻力是流体力学中非常重要的一个基本概念。在现有的流体力学教材中,对流体阻力的介绍相对较少。针对流体阻力问题,分别从牛顿力学和流体力学的角度介绍了流体阻力产生的原因以及它们之间的区别,并介绍了柔性结构的流体阻力。通过这些扩展性介绍,可以让学生对流体阻力问题有更全面的认识和更深刻的理解,也可以提高学生对流体力学的兴趣。

     

    Abstract: Drag force is a fundamental concept of great significance in fluid mechanics. Existing textbooks for fluid mechanics provide relatively limited coverage of drag force. This paper presents explanations of drag force from the perspectives of Newtonian mechanics and fluid mechanics, respectively, and discusses their differences. Additionally, drag force on flexible structures is introduced. Through these introductions, students can develop a more comprehensive and profound understanding of drag force and foster greater interest in fluid mechanics.
