Experimental investigation of Tollmien Schlichting instability and transition in similar boundary layer flow in an adverse pressure gradient
Abstract
The results of a two-dimensional experiment are described, performed in the similar laminar and transitional parts of a boundary layer flow (Hartree beta = -0.14) under natural disturbance conditions. At 23 streamwise stations, mean velocity profiles, power spectra, power distributions across the boundary layer, and amplification spectra are measured and compared with boundary layer and linear stability calculations.
