what's the relation of the viscous hydrodynamic forces and swirl?

Viscous hydrodynamic forces are forces that arise due to the movement of a fluid, such as water or air, over a solid surface. These forces are caused by the viscosity of the fluid, which is a measure of its resistance to flow.
Viscous hydrodynamic forces can significantly influence the behavior of fluid flow. They can cause drag, which is a force that opposes the direction of motion, as well as lift, which is a force perpendicular to the direction of motion. These forces can affect the speed and direction of the fluid flow.
The relationship between viscous hydrodynamic forces and swirl lies in the formation of vortices. As the fluid flows over a surface, the viscosity of the fluid causes it to swirl and create vortices. These vortices can then interact with the fluid flow, causing changes in velocity and pressure.
The viscosity of a fluid directly impacts the strength of viscous hydrodynamic forces. A higher viscosity fluid will experience greater drag and lift forces compared to a lower viscosity fluid. This is because a more viscous fluid resists flow more, leading to a greater force acting on the fluid.
Understanding the relation between viscous hydrodynamic forces and swirl is crucial in many industries, including aerospace, automotive, and marine engineering. Engineers use this knowledge to design more efficient and streamlined vehicles by minimizing drag and optimizing lift. This understanding is also important in the development of turbines, pumps, and other fluid flow systems to improve their efficiency and performance.
