Fig. 1From: From primary instabilities to secondary instabilities in Görtler vortex flowsSketch of the concave wall and coordinates. Also shown are the nonlinear evolutions of Görtler vortices in the laminar simulation (0 <z<12 mm) and in the transitional simulation (12 <z<24 mm) through a sequence of cross sections ranging from x=65 mm to x=320 mm with a step of 28 mm. The contours are coloured by the streamwise velocityBack to article page
