Traditional film cooling with cylindrical-hole faces two challenges: (1) coolant is mainly concentrated downstream of the cooling hole center, and (2) coolant is easily lifting-off the wall at high blowing ratio conditions. Although the installation of vortex generator (VG) helps to enhance the cool...
