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. |
