Abstract

Results of an experimental investigation of the laminar flow of air. The experiments include visual observations of smoke filaments, qualitative velocity fluctuation measurements, and mean velocity profiles. Results are reported over a range of 0. 36 to 1. 02 cm in step height, 0. 61 to 2. 44 m/sec in free stream velocity at the step, and 0. 16 to 0. 51 cm in boundary layer displacement thickness at the step. Laminar flow to reattachment of a free shear layer is observed for subsonic flow and two criteria for which transition to turbulence at reattachment exists are presented.
