HSK 8 | noun | fluid dynamics; the study of forces and motion in liquids and gases
流体动力学 (liútǐ dònglìxué)
流体动力学 is a subdiscipline of fluid mechanics that focuses on the forces acting on fluids in motion and the resulting effects. It underpins aerodynamic design, hydraulic engineering, weather modeling, and biomedical applications such as blood flow analysis. The Navier-Stokes equations are central to the field.
Meanings
- [noun] fluid dynamics; the scientific study of the motion of liquids and gases and the forces acting upon them

Usage Notes
流体动力学 is a precise technical term used in physics, engineering, and applied mathematics. Its scope is often contrasted with 流体静力学 (fluid statics), which deals with fluids at rest. In engineering practice, 计算流体动力学 (CFD) is the dominant modern application, allowing numerical simulation of complex flow fields without expensive wind tunnel testing.
The closely related term 空气动力学 (aerodynamics) is a subdomain focusing specifically on airflow. In research papers, authors may write 流体力学 as a slightly broader term encompassing both statics and dynamics, while 流体动力学 is more precise.
