| Summary: | In the present article, a study of the time-dependent transonic
flow field around an isolated airfoil in a Laval nozzle
is presented. In order to obtain instantaneous flow field information
all over the flow around the blade, the Particle
Image Velocimetry (PIV) method has been employed allowing
one to obtain velocity data in an illuminated light sheet
with a high data acquisition rate and high spatial resolution.
From these instantaneous PIV measurements the mean velocity
field and turbulence quantities of the flow easily can
be obtained by statistical means. |
