Abstract
Supersonic flow around nozzle edge in wind tunnel was tested using the holographic interferometry. M ∞ = 1.56 was the Mach number of undisturbed flow. The nozzle edge was performed under the angle of 90 degrees. Apart the flow field visualization, the accurate flow speed determination in the region of Prandl-Mayer expansion was made possible by holographic interferogram. Theoretical and experimental results show very good agreement. The comparative advantages of holographic method relative to classical method of complex flow fields testing were considered.
