What is the difference between streamlined and steady flow? Is unsteady streamlined flow possible? If yes, could you please explain what are the characteristics of unsteady streamlined flow?

It all started with Henry the second and his Archbishop Becket.boneh3ad said:Why is everyone obsesses with turbulence?
Streamline flow refers to the movement of a fluid in a smooth, continuous manner without any turbulence or vortices. Steady flow, on the other hand, refers to a flow where the velocity and other flow properties do not change with time.
In most real-life scenarios, both streamline and steady flow can coexist. However, steady flow is more common in practical applications, as it is easier to control and analyze compared to streamline flow.
The type of flow is mainly affected by the fluid properties (such as viscosity and density), the shape of the object, and the velocity of the flow. For example, high viscosity fluids tend to have more streamline flow, while low viscosity fluids tend to have more turbulent flow.
Yes, under certain conditions, streamline flow can become unstable and transition into turbulent flow. This can happen when the Reynolds number (a dimensionless number that describes the ratio of inertial forces to viscous forces) exceeds a critical value.
Understanding the differences between streamline and steady flow is crucial in various fields of science and engineering, such as fluid dynamics, aerodynamics, and hydrodynamics. It allows us to accurately predict and analyze the behavior of fluids in different scenarios and design more efficient and safe systems.
