Explain the concept of Boundary Layer in Aerodynamics

The Boundary Layer is a thin region near the surface of a body where viscous effects are significant. It forms due to the no-slip condition, where fluid particles stick to the surface.

Key characteristics include:

  • Velocity gradient from zero at wall to freestream
  • Laminar to turbulent transition
  • Separation under adverse pressure gradients

This concept appears frequently in GATE Aerospace. Would you like me to explain the Blasius solution for a flat plate boundary layer?
