Height of boundary layer calculator

In flight mechanics, the “boundary layer” is a thin layer of air that forms near the surface of an aircraft’s wing or other aerodynamic surfaces as it moves through the air. This layer of air experiences a gradual transition from the free-stream airflow (far away from the surface) to a velocity of zero at the surface itself. The boundary layer plays a crucial role in the aerodynamics of the aircraft.

Rx=Uex/v

  • Rx: Reynolds number. It is a dimensionless value and does not have any units.
  • Uex: external velocity
  • v: Kinematic viscosity of the fluid.
