A stream lined body is defined as the body whose surface coincides with the stream - lines, when the body is placed in a flow. In that case the separation of flow will take place only at trailing edge (or rearmost part of the body).
Behind a stream lined body, wake formation zone will be very small and consequently the pressure drag will be very small. Thus the total drag on the stream lined body will be due to friction (shear) only.

Streamlined Body and Flow Separation
A streamlined body is a shape designed to reduce drag and maximize the efficiency of fluid flow over the surface. The term streamlined refers to a shape that is optimized for smooth and unobstructed flow.
Flow Separation
Flow separation occurs when the flow of fluid over a surface separates from the surface, creating turbulence and increasing drag. Flow separation can occur when the fluid flow encounters an obstacle or change in direction, causing the flow to slow down and separate from the surface.
Suppressed Flow Separation
A streamlined body is designed to suppress flow separation and maintain smooth and efficient fluid flow over the surface. This is achieved through a combination of shape, surface texture, and other design features. When flow separation is suppressed, drag is reduced, and the efficiency of the fluid flow is increased.
Zero Drag
While a streamlined body can reduce drag, it is not possible to achieve zero drag. Some level of drag is always present, even on the most optimized and streamlined bodies. However, by reducing drag to a minimum, a streamlined body can maximize efficiency and performance.
Conclusion
In summary, a streamlined body is defined as a body about which flow separation is suppressed. This is achieved through a combination of design features that maximize the efficiency of fluid flow over the surface. By minimizing drag, a streamlined body can improve performance and efficiency in a variety of applications, from aircraft and automobiles to boats and high-speed trains.
