The Gortler vortices on a concave wall of the three-dimensional convergent nozzle. having rectangular cross section were affected by crossflow in boundary layer with difference of static pressure. Flow visualization by means of smoke-wire technique and hot-wire measurement with I-type probe were carried out for main airstream of 1.5m/s. Using the two-dimensional convergent nozzle and the three-dimensional convergent nozzle, the Gortler vortices transformed remarkably in boundary layer by the crossflow on the curved wall were observed.
