1.	For the same angle of attack and chord length, the boundary layer is thicker in_____(a) Turbulent flows(b) Laminar flows(c) Will be equal in both the flows(d) Depends on the velocity of flowI had been asked this question in an online quiz.Enquiry is from Turbulent Flow in section Incompressible Flow over Airfoils of Aerodynamics
Answer» RIGHT ANSWER is (a) TURBULENT flows For explanation: If we assume the same REYNOLDS number (which is not true, but only for sake of inference), the boundary layer will be thicker in turbulent flows. This is seen from intuition also and theoretically also.The boundary layer thickness will STILL be a few centimeters only.
