Answer – Streamlining in physics refers to the process of shaping an object, such as an aircraft body, to reduce drag or resistance to motion through a stream of air.
Explanation:
Streamlining involves contouring the object in a way that minimizes turbulent wake, which is a significant source of drag. By creating smooth and regular airflow patterns around the object, known as laminar flow, streamlining aims to reduce disturbances caused by the object’s motion through the air. Streamlining principles are essential in optimizing fluid flow, reducing energy losses, and enhancing overall system efficiency in various engineering fields.
In aerodynamics, streamlining principles include rounding the forward part of the object and gradually curving its body towards a tapering rear section to achieve an efficiently streamlined shape resembling a horizontally inclined teardrop. Different streamlined forms are required for subsonic and supersonic speeds due to variations in airflow mechanics at different speeds.
