The purpose of the present study is to investigate two-dimensional unsteady transonic flows in a channel with a sonic throat and a moderately strong normal shock downstream of the throat. The aim of the present work is to obtain a precise description of the unsteady flow in order to characterize the evolution of the boundary layer and the shock in space and time. Shock oscillations whose amplitudes are of about 10 times the order of the boundary layer thickness and frequencies much lower than turbulence frequencies (Strouhal number of about 3×10-4) are investigated. Two optical diagnostic methods were used. The first one is a spark light system coupled with a rotating camera. The second one is an acquisition method using a two-component laser Doppler velocimeter synchronized with a reference signal. Continuous and unsteady pressure measurements were performed.
