Comment on 'Further experiments on shock-tube wall boundary-layer transition'

A critical appraisal is made of Chabey and Cook's (1983) work on the characterization of the transition in the unsteady wall boundary layer behind a moving shock in a classical shock tube. Attention is given to apparent contradictions, in light of interpretations advanced by Thompson and Emrich (1967) and Brun et al (1978). It is noted that all experimental results obtained in the past at one unique measurement station cannot be used to correctly describe the transition phenomenon.
