Visualization of the pressure fields of gas streams by the method of holographic interferometry

  • 22 Accesses

Abstract

The pressure field is determined from the deformation of an assembly of membranes uniformly distributed over the walls confining the stream. The deformations are recorded by the method of two-exposure holographic interferometry. The possibilities of the method are illustrated on the examples of flow over a Zhukovskii profile and flow in a nozzle. Direct visualization of the isobars in the field of flow is accomplished.
