The impact of inlet flow conditions on the aerodynamic performance of a NACA submerged intake for ground vehicle applications [PDF]
, 2013 Results are presented following a series of experimental measurements on a submerged NACA type intake orientated between ±30 degrees yaw to the free stream in an atmospheric boundary layer wind tunnel at a unit Reynolds number of nominally 1 x 106.
