摘要: The particular problems associated with the experimental analysis of propagation pressure waves are addressed and measurements obtained on a long shock tube (the STARLET facility) presented. It was possible to show effects unsteady friction travelling in tunnel at scale 1/50. transition flow from laminar turbulent state plays an important role shape profiles recorded tube. use wavelets for filtering data has given particularly good results.
